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. The 20 different amino acids. 7.5.1: Explain the four levels of protein structure, indicating the significance of each level.. Peptide bonds link the amino acids together . Polypeptide with five amino acids. . The 20 different amino acids. 7.5.1: Explain the four levels of protein structure, indicating the significance of each level.. Peptide bonds link the amino acids together . Polypeptide with five amino acids. . Importance, Characteristics, Structure, Classification, . Denaturation. Importance. Major structural components of animal tissues. Involved in the maintenance of life processes as communication (nerves), defense (antibodies), metabolic regulation (hormones), biochemical catalysis (enzymes), and oxygen transport (hemoglobin). B.2. Properties of 2-amino acids . (B.2.2). Zwitterion. (dipolar) . amino acids contain both acidic and basic groups in the same molecule . therefore, are . amphoteric. in nature (capable of behaving as acids or bases). 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. 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. Polypeptides . are chains of amino acids linked together by condensation reactions. the main, or only, component in proteins. Some proteins are composed of only one polypeptide chain, while others are made of 2 or more. 6. 6.1 Differentiate . between essential amino acids and nonessential amino acids.. 6.2 List . the functions of protein in the body.. 6.3 List . the steps for protein digestion and absorption in the body. . 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.. proteins of cereals and legumes..
