proteins
1 LECTURE 6: PROTEINS Protein Outline 2 Proteins (structure and function) ?Major roles in physiology & structural frameworks ?Amino acid structure ?Levels of structural organization: (primary, secondary, tertiary, quaternary) ?Properties (relate to structure) ? Major classes of proteins Objectives 3 1. Describe the structure of amino acids 2. Outline how proteins are formed by peptide bonds. 3. Describe how proteins are organized at the primary, secondary, tertiary, quaternary levels. 4. State the functions of proteins 5. Classify proteins according to structure/solubility, composition, function. Proteins 4 ?More than 50% of the dry mass of an organism consists of proteins.
