4 calories per gram The main function of protein is to build and repair body tissues If carbohydrates and fat are not available your body will use protein Is this a good thing You must eat protein . B. Suarez, R. Martinez, O. Diaz, H. Jones, T. Ashraf, E. Priddis, K. Durham, Undergraduate Biology Research, Cochise Community College, Sierra Vista, AZ . INTRODUCTION.  . Genomic and proteomic studies can reveal multi-dimensional aspects of biological model organisms. DNA sequencing and short tandem repeats are utilized to characterize organism’s phylogenetic relationships; another approach is to study their various proteins. Many genomic studies utilize extraction and amplification of nucleic acids to help make detection more straightforward. There is no proteomic procedure similar to PCR that would identify proteins at their naturally existing concentration, as well as the presence of many other proteins for comparative studies. Most methods for studying proteins revolve around running 1D, 2D, or 3D gels, and comparing and identifying similar proteins. . Dina N Kovarik, MS, PhD. Digital World Biology. Updated . April 24, 2015. Fluorescent Proteins are Valuable Tools. Locate proteins in the cell. Track the migration of cells. Reporter of expression. Sister centromeres . Levels of Protein Structure. Primary 1º Structure. The primary structure is simply the sequence of amino acids in a protein.. Chains of amino acids are written from the amino terminus (N-terminus) to the carboxyl terminus (C-terminus).. 2. Proteins (. Polypeptides. ). Chains of Amino acids (. 20. different kinds). bonded together by . peptide bonds. . (. polypeptides. ). Made of . Nitrogen, Carbon, Oxygen, and Hydrogen. Functions:. Unit objectives:. Identify amino acid classifications based on nutritional use and chemical properties of side chains. Describe the primary, secondary, tertiary and quaternary structures of proteins. Amino . Acids. In a transamination reaction, . aspartate transaminase (AST) . catalyzes the reversible transfer of an amino group between glutamate and aspartate.. an . α. -amino group is transferred from an amino acid to an . June 12, 2018. Why PPI?. Protein-protein interactions determine outcome of most cellular processes. Proteins which are close homologues often interact in the same way. Protein-protein interactions place evolutionary constraints on protein sequence and structural divergence. Protein Synthesis (Gene Expression) Notes. Proteins . (Review). Proteins make up all . living. materials. Proteins are composed of . amino acids. – there are . 20. . different amino acids. Different . A nutrient found in all living things. It contains nitrogen and is responsible for the formation, maintenance, and repair of the body’s tissues/ It can also be used for energy. CHNO. Amino acids . proteins of milk, meat and eggs.. Milk composition. Deficient in iron and vitamin C. Milk proteins. Total protein content in milk – 2.9 – 3.5%. Two major types of milk protein. Caseins (80%). Whey proteins: (20%). Most abundant molecule in cells making up 50% or more of their dry weight. Every protein has a unique structure, or shape. Allows it to perform a specific function. Enzymes are proteins that function as catalysts for many reactions in foods. Proteins are polymers of amino acids produced by living cells in all forms of life.. A large number of proteins exist with diverse functions, sizes, shapes and structures but each is composed of essential and non-essential amino acids in varying numbers and sequences.. Protein . is a very important nutrient. It makes up most of our body cells, tissues and fluids. .. Protein . Deficiency. -Leads to Kwashiorkor in children Happens mostly in impoverished countries where there is a lack of protein rich foods. . The concentration of many of these are affected by pathological processes; they are therefore measured.. They contain disulphide bonds.. Functions of plasma proteins include:. Transport. Maintaining plasma .
