Proteins

Proteins are a macronutrient that provides the body with energy, they are the building blocks of the tissues in the body. One of the most important functions of proteins is to build up, repair, and replace the tissues in the body. The muscles, organs, and some hormones are made up of mostly proteins. Proteins are made up of amino acids, and there are 20 different types of amino acids some in which our bodies doesn’t make. The amino acids that the body doesn’t make are called essential amino acids. The human body produces non essential amino acids so they aren’t required in our diet. There are two types of proteins complete and incomplete proteins. Complete proteins have all the essential amino acids and the incomplete proteins are missing at least one or more of the essential amino acids. There are many risks associated for over consuming proteins, for an example, a greater risk of developing osteoporosis, kidney problems, and some cancers. Although more common in undeveloped countries, there are many risks from protein deficiencies. Like, fatigue, swelling in both the hands and feet, wasting and shrinkage of the body’s muscles and tissues, and weakening of the immune system. It is recommended that 10-30 percent of your daily calories intake should be proteins. Females ages between 14 to 18 should consume 46 grams of proteins a day, males ages between 14 to 18 should have 52 grams of proteins a day, women ages 19 to 70 plus should also get at least 46 grams of proteins a day, men ages between 19 to 70 plus should have 46 grams of proteins a day. Proteins can be mainly found in animal based foods like meat, eggs, milk, cheese, fish, and poultry. Proteins are very important to the functioning of the human body. It is very important to get the right amount of proteins to avoid the many different types of health problems associated with protein deficiency.

Secondary Structure Inside Ribosome

...Biogenesis of the T1-S1 Linker of Voltage-Gated K+ Channels Running Title: The T1-S1 Linker of nascent Kv1.3 Key words: Protein folding, nascent peptides, potassium channel biogenesis, T1 domain, S1 transmembrane segment 1 Abstract In the model derived from the crystal structure of Kv1.2, a 6-transmembrane voltagegated potassium channel, the linker between a cytosolic tetramerization domain, T1, and the first transmembrane segment, S1, is projected radially outward from the channel’s central axis. This T1-S1 linker was modeled as two polyglycine helices to accommodate the residues between T1 and S1 [Long et al. (2005) Science 309, 897-903], however, the structure of this linker is not known. Here, we investigate whether a compact secondary structure of the T1-S1 linker exists at an early stage of Kv channel biogenesis. We have used a mass-tagging accessibility assay to report the biogenesis of secondary structure for three consecutive regions of Kv1.3, a highly homologous isoform of Kv1.2. The three regions include the T1-S1 linker and its two flanking regions, α5 of the T1 domain and S1. Both α5 and S1 manifest compact structures (helical) inside the ribosomal exit tunnel, whereas the T1-S1 linker does not. Moreover, the location of the peptide in the tunnel influences compaction. 2 Introduction Voltage-gated K+ (Kv) channels are critical to the normal functioning of excitable and non-excitable cells (1,2). Defects in their biophysical properties,......

Protein Article Research

...Protein is found in every cell, muscle and tissue of our body and is also present in many of the foods that we eat daily. Protein is a major component of all muscles, tissues and organs and is vital for practically every process that occurs within the body such as metabolism, digestion and the transportation of nutrients and oxygen in the blood. The protein in our body is essentially the same as the protein in our food, except that it is structured differently. (Unknown author- (2001-2010) Protein - an introduction to protein in the diet) Based upon chemical composition, proteins are divided into two major classes: simple proteins; which are composed of only amino acids, and conjugated proteins; which are composed of amino acids along with additional organic and inorganic groupings, also known as prosthetic groups. (The Columbia Electronic Encyclopedia, 6th ed. Copyright © 2007, Columbia University Press) Amino acids are the building blocks of all proteins. Amino acids are chemical compounds containing carbon, hydrogen, oxygen and nitrogen, which combine together into different structures to form the various types of protein that the body needs. The body requires 20 different amino acids, 8 of which are referred to as essential amino acids, which cannot be synthesized by the human body. Non-essential amino acids can be synthesized by body but this does not mean they are less important because they are. The body is capable of producing enough protein to meet the demands......

The Living Cell Biology

...David Hrobochak Biology 1740 Kirstin Purcell Common Book Assignment 2 The reasons you can get more proteins from the genes are because each gene is individual, and each protein has a different function. Some proteins are responsible for structural support while others are responsible for defense against germs; others are involved in bodily movement. There are 4 levels of protein structure. The first is primary, which is the sequence of amino acids that make up protein. Different proteins will have different sequences of amino acids. Secondary structures are the coils or folds in the helix due to hydrogen bonding. Tertiary structures are just further folding of the polypeptide and quaternary structures are 2 or more polypeptide units folding together. The folding of all these amino acids causes the multiplication of proteins. I agree that nature plays a part of our development. Look at the scientific theory of evolution. Are we really descendents of apes? From a scientific perspective this is conceivable. The outbreak of Malaria is tolerated in most countries, but in Africa it is a widespread pandemic. This is an example of genetic variation. I believe 100 percent of us are genetic. We are created through genetic variation and the inheritance of variation. Natural selection is how we can cope with environmental changes. This is why certain individuals can deal with extreme temperatures better than others.

...element, which have differing numbers of neutrons. Atoms of a particular element by definition must contain the same number of protons but may have a distinct number of neutrons which differs from atom to atom, without changing the designation of the atom as a particular element. The number of nucleons (protons and neutrons) in the nucleus, known as the mass number, is not the same for two isotopes of any element. Components of nucleic acid 1). DNA = deoxyribonucleic acid - genetic material that stores information to synthesize proteins and to replicate new DNA. The genetic code is based on four nitrogen bases: adenine (A), thymine (T), guanine (G), cytosine (C). A bind with T and G binds with C.2). RNA = ribonucleic acid - helps in synthesizing proteins. There are three main types of RNA.a. mRNA - messenger RNA, copy of the DNA, sent out into the cytoplasm.

...specific antibody (this might depend on the experiment as some might prefer different antibodies), and large quantities are made. Disadvantages are that the affinities of the antibodies differ, a good amount of a specific antibody can’t be made alone unlike monoclonal, it is less reliable, and the same sample can’t be guaranteed each time unlike the monoclonal which can bring similar clones months later. 3) The GFP-HDAC3 overlaps the DAPI where the nucleus is. This shows that HDAC3 is a nuclear protein. However, some deletions show that the nucleus has gone smaller while others show that the nucleus has gone larger. The goal of this experiment was to find out how the different portions of the protein affected localization in the cell. The experiment does show that there was a significant effect. 4) Sense: 5’ aagccccatcgcctggcattg 3’ Linker Loop: 5’ uucaagaga 3’ Antisense: 5’ caatgccaggcgatggggctt 3’ Poly U: UUUUU The goal of the knockout would be to see if the removed proteins had any effect on the function of the cell.

Biology

...Eukaryotic cells solved the problem of moving proteins and organelles from one part of the cell to another, faster than would occur by diffusion? And give a specific example to illustrate how a protein may be moved from part of the cell to another. The huge volume inside a eukaryotic cell is compartmentalized into a large number of bacterium-sized parts. Because eukaryotic cells are subdivided, the molecules required for specific chemical reactions are often located within a given compartment and do not need to diffuse long distances to be useful. Additionally, compartmentalization increases the efficiency of chemical reactions. First, the substrates required for particular reactions can be localized and maintained at high concentration within organelles. Second, groups of enzymes that work together can be clustered on internal membranes instead of floating free in the cytoplasm. Clustering these molecules increases the speed and efficiency of the reactions, because reactants have shorter distances over which to diffuse or be transported. ii. An example to illustrate how a protein may be moved from part of the cell to another. For example, in localization sequencing a protein might be sent to the nucleus or marked for secretion outside of the cell. Additionally, in the SH2 domain , a protein domain is present in many signaling proteins. For example, the SH2 binds a short amino acid sequence containing a phosphotyrosine, and moves a protein containing it to sites in......

Cellulite

...Formation of Cellulite Explained Cellulite is not restricted to fat people. Even lean people can suffer from it. Losing cellulite is more difficult than losing fat. Cellulite is the swelling of the fat cells, which then appear as bumps on the body, causing what is known as the 'dimpling effect', or the 'orange peel effect', because the cellulite affected area resembles an orange peel. In the following paragraphs we will find out the exact nature of cellulite and how it is formed. Once that is clear, it will be easier to understand how to get rid of it. Appearance of Cellulite on the Skin The skin is made up of many different layers, called 'dermis'. The fat cells that are under the skin are connected to the skin with the help of a layer called 'septa', which is fibrous in nature. This layer forms a wall between the fat cells and the skin. But when this layer beaks down, the fat cells which expand, do so directly against the skin, so that there is no layer between the two. Due to this the skin develops pits and valleys, and resembles an orange peel, or cottage cheese, or has a dimpled appearance. The appearance of cellulite is different in men and women, but the difference is not very significant. Causes of Cellulite The causes of cellulite in men and women differ. In women, the hormonal changes during menstruation, menopause, pregnancy, etc., which regulate the flow of blood, lymphatic drainage and fat, are mainly responsible for the formation of cellulite.

Protein Article Reasearch

...Protein Article Research Protein is an essential part of a healthy diet. It is made of different combinations of 20 different amino acids. Protein is found in every cell, tissue, and organ of the body. It is important to consume an adequate amount of protein because our bodies are constantly using the protein we digest to make more amino acids. Some amino acids cannot be produced by the body and it is essential that our diet contain them. There are different types of protein and they are labeled according to the amount and type of amino acids they contain. The first is known as a complete protein source. Complete protein sources contain all of the essential amino acids. They are also known as high quality proteins. The other is known as an incomplete protein source. This is a protein source that lacks one or more of the essential amino acids. Proteins can be consumed in conjunction in order to make up all of the essential amino acids. This is called complementary proteins. ("Center for Disease Control and Prevention", n.d.). Finding the proper balance of protein is extremely important for overall health. Eating a diet high in protein poses many health risks. The risk factor for heart disease and cancer is increased when a diet contains too much protein. Animal proteins contain a higher fat content which leads to higher cholesterol which plays a large role in heart disease. Research shows that people who consume a high amount of protein tend to have a......
