PPT-What are proteins?

Large organic compounds which are responsible for catalyzing biochemical reactions as well as providing structure mobility and function for cells What is surface tension Have you ever seen one of these insects The . 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 .

Proteins account for more than 50% of the dry mass of most cells. Protein functions include structural support, storage, transport, cellular communications, movement, and defense against foreign substances. 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 . 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 . 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. Each amino acid (aa) shares a common structure; i.e. an amine (NH. 2. ) group, an acid group (COOH), and a central carbon atom bonded to hydrogen and to a side chain (R).. The side chains qualify aas as acidic, basic, neutral, aromatic, and sulphur-containing amino acids.. 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 . Unit 1 Advanced Higher. Miss Aitken. Pages 16-25. Textbook. Proteomics. Genome:. complete set of DNA. Comprises of coding and non-coding areas. 20-25000 genes in human genome.
