PPT-Lesson 5 – Proteins

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 Nterminus to the carboxyl terminus Cterminus. 2. Proteins. Proteins are polymers made of monomers called amino acids. All proteins are made of 20 different amino acids linked in different orders. Proteins are used to build cells, act as hormones & enzymes, and do much of the work in a cell. 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 . PROTEINS – (DR. TRAISH) Introduction to Proteins - Proteins are abundant and functionally diverse molecules - They participate in cell regulation at all levels - They share a common structural 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 . In order to survive, the human body needs the nutrients found in food. These nutrients, which perform a number of life-sustaining functions in the body, are divided into 6 main categories: carbohydrates, proteins, fats, vitamins, minerals and water. Each has a unique function in the normal growth and repair of the body.. 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 . Chromatin is made of repeating units of nucleosomes, which consist of 146 base pairs of DNA wrapped around an octamer of four core . histone proteins (H3, H4, H2A and H2B). Introduction. Histones are a special group of proteins found in the nuclei of eukaryotic cells responsible for DNA folding and chromatin formation.. 4b.4. The Triple-Note-Tote. Topic. Details. Mnemonic. Triple-Note-Tote. Objectives. Recognize the importance of taking effective notes for remembering information. Organize ideas from an article using the Triple-Note-Tote. Objectives:. Know the basic terminology related to fats and proteins. . Know the classifications of fats and proteins.. Basic terminology related to fats and proteins. Fat. denotes an ester composed of glycerol (tri-hydric alcohol) and three fatty acids of (triacylglycerol or triglycerides).. 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. Proteome:. Entire set of proteins that can be expressed from a genome.
