Document Summary
Unit 4 overview of protein and vegetarian diets. Chemical bonds: h (1), o (2), n (3), c (4) Proteins are made up of amino acids. Each amino acid is composed of a carbon (c) backbone, amino group (nh2), acid group (cooh), and a side group (side chain), unique to it. Glycine is the simplest amino acid, which has a hydrogen as its side group. There are 20 nutrition-related amino acids, 9 essential (must be supplied by the diet) Unique side groups of the amino acids in a chain, attract and repel each other contributing to the shape as some side chains are hydrophilic and some are hydrophobic. Function of a protein is defined by its sequence and folding (some form hollow balls to carry things, some are long like tendons) Some polypeptides function individually while some associate with other polypeptides to form working complexes. Some proteins require minerals to activate them.
