A.

1. Explain differences between the oxygenated and deoxygenated states of two hemoglobin.
With Oxygenated blood the heme has a plantar shape as for Deoxygenated the heme is domed, cooperativity causes the shape. Another difference is color. Heme is bright red when bound to oxygen, as for deoxygentaed blood the heme is purple to bluish in color.

2. Explain how pH impacts the binding and
release of oxygen by hemoglobin
CO2 in the blood creates a decrease in pH, this causes the hemoglobin to release their oxygen molecules. A decrease in CO2 causes the pH to increase, which causes the hemoglobin to pick more oxygen molecules.

3. Explain how diseased cells differ from normal red blood cells in their capacity to transport oxygen.
They differ by its shape. Normal red blood cells are concave disk shape. The diseased cell has a sickled shape. The sickled shape causes the cells to get stuck in the blood vessels, thus preventing them from bringing oxygen to other parts of the body. 4. a. Identify the type of inheritance seen in sickle cell anemia.

Vitamins

...Fat and Water-Soluble Vitamins Carolyn Johnson SCI/241 February 27, 2014 Anna Brashier Fat and Water-Soluble Vitamins Vitamins are organic compounds that are essential in the diet in small amounts to promote and regulate body processes necessary for growth, reproduction, and health maintenance. Vitamins are classified based on solubility, some are soluble in water known as water-soluble vitamins, while others are soluble in fat known as fat-soluble vitamins. Vitamins promote and regulate the body activities. Each vitamin has at least one important function. Some are needed for vision health, blood clotting, and bone health, some vitamins are needed for organ health and system function. (Grosvenor, 2012, Chapter 7). Some vitamins have coenzymes and few others function as an antioxidants. (Grosvenor, 2012, Chapter 7). Fat-soluble vitamins are vitamins A, D, E, and K and are found along with fats in foods. Fat soluble vitamins are soluble in fat, these vitamins can be stored in the liver and in fatty tissues. High nutrient sources for vitamin A can be found in Carrots, squash, apricots, and other orange and yellow vegetables. High nutrient sources of vitamin D: sunlight, liver, egg yolks, and oily fish such as salmon naturally have vitamin D. Vitamin D fortified foods are milk, margarine, some yogurts, cheese, and cereals. Vitamin E is found in nuts, seeds, canola oil, safflower oil, sunflower oil, and leafy green vegetables like spinach, mustard greens, and wheat germ...

Vitamins

...believe that they consume an inadequate amount of vitamins to sustain a healthy lifestyle or that ingesting an excessive sum of certain vitamins will improve their health and combat certain diseases. However, this is simply not the case. If a person eats an adequate diet, with foods rich in vitamins, which most Americans do, there is no need to take supplements or consume fortified foods. More so, some vitamins if taken in excess can actually be counterproductive and cause health problems. To further understand, once water soluble vitamins are ingested into the body they move directly to the blood stream, where they are able to move freely about. Whereas, fat soluble vitamins must first travel through the lymph then into the blood and can only be transported with the help of protein. More so, the kidneys, which monitor the flow of blood, detect and remove necessary amounts of water soluble vitamins, but sometimes when overconsumption of water soluble vitamins are ingested, a large excess of vitamins are released, which overwhelm the system, creating an adverse effect. Although, fat soluble vitamins stay in the system longer causing more harmful affects when people excessively take them; some water soluble vitamins can still be detrimental to the human system. Some of the water soluble vitamins that may be toxic when consumed in overabundance are B(6), folate, and vitamin C. When people intake too much B(6) vitamins there can be neurological damage, especially when intakes...

Vitamins

...“Vitamins were first introduced in 1911 by the Warsaw-born biochemist Casimir Fink (1884-1967). Nutrition is essential for growth, development and well-being. Behavior to promote good health should start early in life with breastfeeding and continue through life with the development of healthy eating habits. It is also the responsibility of the parents to continue to contribute to young people’s growing knowledge of nutrition, not only by providing nutritious meals in the home but also by periodically explaining the importance of vitamins, minerals and other essential vitamins. Too much or too little intake of vitamins can lead to serious illnesses. A person can become vitamin deficient if they are lacking the minimum amount of certain vitamins needed by the body to maintain regular good health. If long term vitamin deficiency occurs, a deficiency disease can develop, and this can also lead to probable death. Unlike some other food substances, such as protein and carbohydrates, of which the body needs to consume large regular quantities, vitamins are needed in small quantities. Hence, vitamins, minerals and supplements should be an important part of our daily diet in order to achieve a healthy lifestyle and to avoid vitamin deficiencies. According to researcher Meirner “a deficiency in either vitamin B12 or folate may due to inadequate dietary intake, malnutrition, chronic, significant alcohol intake, problems with gastrointestinal absorption, history of gastric surgery, sever...

...Soluble vitamins Vitamins are a valuable component to a healthy diet, because our bodies cannot make them or our bodies cannot produce enough of them to provide adequate nutrition to our cells. Vitamins are essential for everyday body functions such as cell growth, blood cell production, hormone production, and metabolism. Vitamins can also affect body systems such as the reproductive system, circulatory system, and the immune system. Fat soluble vitamins consist of vitamin A, D, E, and K. These vitamins only dissolve in fat not in water and are stored in fatty tissues as well as the liver. These vitamins can be stored for long periods of time and people consuming a well-balanced diet do not need to supplement them. It is more common for people to have too much of these of these vitamins in their system which can be toxic than with the water soluble vitamins. Vitamin A is found in animal products such as liver, egg yolks, dairy products, and fish. Vitamin D can be found in dairy products such as milk, but also 10 minutes in the sun can give you your daily dose. This vitamin helps with the hardening of bones and teeth. Vitamin E is considered an antioxidant and helps to protect vitamins A and C. it also promotes the metabolism of iron and helps to maintain the nervous system.

Vitamin a

... D20131063419 GROUP A Summary Writing Vitamin A Vitamin A is found only in yellow animal fats, in egg-yolk, milk and cheese. It is particularly plentiful in fish-liver oils, hence fish-liver oils are used for preventing and curing illness caused by lack of vitamin A. In a well-fed, healthy human being, the liver can store up sufficient vitamin A to meet the body's requirements for six months. Although vitamin A itself is not present in plants, many plants produce a substance called carotene, formed from leaf-green which our bodies can convert into vitamin A. Carotene is the yellowish-red colouring matter in carrots. The greener a leaf is, the more carotene it usually contains. Hence the importance of green, leafy vegetables in the diet as a source of carotene. Tomatoes, papayas, mangoes and bananas contain more carotene than most other fruits. Red palm oil contains so much carotene that it is used instead of cod-liver oil. Thus, it is very valuable, both as a food-fat and for deep-frying. Vitamin A and carotene are insoluble in water and they are not destroyed by heat unless oxygen is present. Boiling in water, therefore, does not destroy much vitamin A or carotene. Vitamin A encourages healthy growth and physical fitness. Young animals soon stop growing and die if vitamin A is not present in their diet. This vitamin keeps the moist surfaces lining the digestive canal, the lungs and air passages healthy. It also helps...

...Vitamin Water the real truth Abstract According to grabstat.com water is the world most popular beverage consumed. There is no surprise why popular beverage manufacturers such as Coca Cola and Pepsi capitalize on this fact to market their vitamin water products. Although these manufacturer market vitamin water as a "healthy beverage", the product labels say otherwise. When comparing the top three popular brands SoBe Life Water by South Beach Beverage Co, Dasani Plus by Coke and Aquafina Alive by Pepsi, the sugar and caloric content for a 8 fl. oz. serving size, with 2.5 servings per container are as follows 10 grams/ 0 / 0 and 40 calories/ 0/ 0 respectively. The sodium content: 35mg / 25mg / 65mg; Total Carbohydrates: 10g / 1g / 0g respectively. The actual amount of sugar consumed in each drink would be multiplied by 2.5, since consumers drink more that the eight ounces in one sitting. For a diabetic patient consuming this amount of sugar daily would cause serious health risk. Patients with other co-morbidities such as hypertension and obesity are also at risk for worsening conditions when consuming these beverages in ignorance. Vitamins are essential for our bodies' growth and development. There are thirteen vitamins that our bodies need, they include the fat soluble vitamins A, D,E and K and the water soluble B-vitamins (thiamine, riboflavin, niacin, pantothenic acid, biotin, vitamin B-6, vitamin B-12, folate) andvitamin C.

...Soluble Vitamins Katharine Jones SCI/241 September 22, 2013 Water soluble and fat soluble vitamins are both needed in order for our bodies to not only survive but to thrive as well. Water soluble vitamins are vitamins that are stored within our bodies and are needed daily. If we consume too much water soluble vitamins they will then be excreted through our urine. Water soluble vitamins are metabolized by the process of digestion and then absorption. Fat soluble vitamins are vitamins that are soluble in fats. Foods cooked with these vitamins will not lose their vitamins after being cooked. Vitamins A, D, E, and K are considered the fat-soluble vitamins. There are many sources which you can find these vitamins in. Other than supplements you can find these vitamins within foods such as, dark leafy vegetables (vitamin A), in milk and dairy products (vitamin D), in vegetable oil (vitamin E), and vitamin K can be found by eating spinach. The water soluble vitamins are the B complex vitamins and vitamin C. These vitamins can be found within such things as, citrus fruits, liver, breakfast cereals, eggs, and dry, long grained rice. Water soluble vitamins do not run the risks of toxicity because when taken in excess they will be excreted through the kidneys and leave the body through urination.

...Vitamins in Fruits & Vegetables 12/07/2011 Vitamins in Fruits & Vegetables The benefits of consuming fresh produce are an increased vitamin intake, no negative effects of additives and weight control. The purpose of a balanced and healthy diet is to include a variety of vitamins and minerals. Most people know that macro-nutrients such as carbohydrates, protein and fat are necessary components of a diet. While that is true, vitamins are essential micro-nutrients, which are also important parts of a healthy diet and can have a large effect on health and well-being. Vitamins are involved in protecting the body from oxidative damage and gene expression, according to Carol N. Angstadt, Ph.D., of the Department of Biomedical Sciences at Allegheny University of Health Sciences. Fresh vegetables and fruits include vitamins that are good for your health. They are important because they are contributors to the body’s daily function and are essential to its growth and repair. They are essential because the body does not produce vitamins naturally, and they must be obtained from foods. Most discoveries about the human need for essential vitamins were made as a direct result of their deficiency. As illustrated in the nutrition manual "Modern Nutrition in Health and Disease," the importance of vitamin C was discovered because 18th century sailors who suffered from scurvy at sea were cured when they received citrus juice as a remedy. Advantages of good vitamins intake...

In this report we explored factors that have led the brand to build its equity since its introduction in 2013. It was initially introduced as an Enhanced Water product with 6 essential vitamins and minerals and came in only 5 flavors. It is the only Enhanced Water category product that exists in Pakistan. This is where it has gotten an edge over its competitors. However, they believe that the target market is still unaware of what the product exactly is, despite of being aware of the Brand’s existence. Currently, Vitamin Water is at its introductory phase where it is looking to generate leads and educate its audience about the Enhanced Water Product category. They have started conducting researches for long-term plans and to evaluate their existing market performances.

Vitamin C

...Vitamin C Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that is naturally present in some foods, added to others, and available as a dietary supplement. Humans, unlike most animals, are unable to synthesize vitamin C, so it is an essential dietary component. In some settings, vitamin C serves as a cofactor helping a specific enzyme perform its job, but in others, it acts as an antioxidant participating in more general ways. Vitamin C loses electrons easily, a characteristic that allows it to perform as an antioxidant. Vitamin C is like a bodyguard for water-soluble substances. In the cells and body fluids, Vitamin C protects tissues from the oxidative stress of free radicals thus may play an important role in preventing diseases. Food sources for Vitamin C come from fruits and vegetables mainly. Broccoli, carrots, potato, tomato juice, banana, orange, strawberries, watermelon, cheese, citrus fruits, cabbage-type vegetables, dark green vegetables, cantaloupe, lettuce, tomatoes, papayas and mangos are all significant sources of Vitamin C. Functions of Vitamin C in the body include collagen synthesis, which strengthens blood vessel walls, forms scar tissue, provides matrix for bone growth. More functions include antioxidants, thyroxin synthesis, amino acid metabolism, strengthens resistance to infection, helps in absorption of iron.  Ascorbic acid is absorbed in the body by both active transport and simple diffusion.

Vitamin B

...Amanda Phillips Research Paper Professor Perry Fundamentals of Human Nutrition April 2, 2013 Vitamin B Complex is made up of several B vitamins. They are essential for the bodies normal functions. B vitamins can be referenced by many different names such as vitamins B1, B2, B3, B5, B6, B7, B9, and B12. There are also their scientific names: thiamin (B1), riboflavin (B2), niacin, nicotinamide or nicotinic acide amide (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folic acid or folate (B9), and cobalamin (B12). Each vitamin B has its role in our health and is important for a healthy body. For example Vitamin B1, thiamin, plays many key roles in the body: metabolic cycle for generating energy, aids in the digestion of carbohydrates, essential for the normal functioning of the nervous system, muscles and heart; stabilizes the appetite; promotes growth and good muscle tone. Having a B1 deficiency may lead to mental depression and constipation; weakness and feeling tired; nervous irritability; insomnia; the loss of appetite; paralysis and loss of weight; or even heart and gastrointestinal problems. Vitamin B2, riboflavin, is necessary for carbohydrate, fat and protein metabolism; aids in the formation of antibodies and red blood cells; maintains cell respiration; necessary for the maintenance of good vision, skin, nails, and hair; alleviates eye fatigue, promotes general health.
