CARBOHYDRATE METABOLISM Carbohydrates are found as monosaccharides, disaccharides, and polysaccharides or complex carbohydrates. They function in energy storage (starch&glycogen), signaling (glycoproteins and glycolipids, e.g. blood group determinants), fuel the nervous system and muscle (and virtually all cells, although there are distinct cell type specific differences in choice of primary fuel molecule), are parts of nucleic acids (genes, mRNA, tRNA, ribosomes), and as cell surface markers

role in the cells? Cells use carbohydrates as their main source of energy; however, glucose is the only form that can enter the cell and actually gets used. Other types of carbohydrates, such as fructose, lactose, sucrose… must first be broken down into glucose before being used by the cell. To maintain a constant supply of energy, the level of glucose in the blood must be balanced. Too many carbs can lead to obesity and blood pressure spikes. Some of the carbohydrates that aren't used up, are stored

Metabolism: Transformations and Interactions I. Chemical Reactions in the Body Plants use the sun’s energy to make carbohydrate from carbon dioxide and water. This is called photosynthesis. Humans and animals eat the plants and use the carbohydrate as fuel for their bodies. During digestion, the energy-yielding nutrients are broken down to monosaccharides, fatty acids, glycerol, and amino acids. After absorption, enzymes and coenzymes can build more complex compounds. In metabolism

macronutrients such as carbohydrates, proteins and fats; and the micronutrients: vitamins and minerals. . Macronutrients Macronutrients as its name implies are the molecules that are needed by the body in big amounts. They occupy the biggest portion of the nutrients absorbed by the body from the food that was eaten. 1. Carbohydrates Carbohydrates mean carbon with water. Plants use sunlight in the process of photosynthesis to convert water and carbon dioxide into carbohydrates and oxygen. When

Energy Metabolism of the Canis familiaris Kristy Stewart 17153535 1. Introduction Understanding where, and how the energy that enables life to exist comes from, known as energy metabolism (Cox and Nelson 2013), is integral to understanding health and nutrient needs for organisms. The study of energy metabolism is applicable in many areas; medicine and agricultural livestock health and production are two major applications for this discipline of study. There are different forms of energy

enzyme activator. Zinc transports carbon dioxide, protein synthesis, the storage of insulin, sexual function, healing of wounds and carbohydrate metabolism. Iron transports oxygen and electrons, enzyme activator and formation of hemoglobin. Manganese utilizes vitamin B1, production of fluids in joints, protein metabolism, connective tissue and carbohydrates metabolism. There are several other minerals these are just to name a few and the importance of them in our bodies. They help in enzyme reactions

CARBOHYDRATES (sugars, starches, cellulose) * Made from joining H2O and CO2 by plants during photosynthesis * Monomer: Simple sugars: CH2O (ratio of one carbon and one oxygen to every 2 hydrogen) * Three main functions: energy for cells, structural support, cell-cell communication * Three main sources of carbohydrate: starches, sugar and cellulose. 3 Kinds of Sugars A. Monosaccharides (Simple sugars) – Building blocks of more complex carbohydrates. * Glucose (dextrose

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

The main function of carbohydrates are they are the production and storage of energy; the energy they produce is used by the body tissues. They are also served as carbon skeletons that can be rearranged to form other molecules that are important for biological structures and functions. Carbohydrates are the main energy source for the human body, they are organic molecules in which carbon, hydrogen, and oxygen
