APhA CH 5 – Biochemistry - Summary First Part by Pearl Chris MAJOR GROUPS OF BIOMOLECULES: 1. Amino acids. 2. Fatty acids. 3. Carbohydrates. 4. Nucleic acids. These building blocks in turn form major macromolecules: 1. Proteins and enzymes. 2. Lipids. 3. Glycogen and starch. 4. RNA. 5. DNA. Enzymes are primarily catalysts of various reactions needed to carry out- 1. Cellular development. 2. Cell metabolism. 3. Growth and differentiation. 4. Cellular regulation. 5. Cell death (apoptosis). CHEMISTRY OF BIOMOLECULES: PROTEINS: Amino acids – building blocks of protein. All amino acids contain amino group and carboxylic acid group. Two large groupings of amino acids depending on amine group: 1. Primary – nitrogen atom has only one bond to carbon atom. 2. Secondary – nitrogen atom is bonded to two carbon atoms. Nine essential amino acids: 1. His 2. Ile 3. Leu 4. Lys 5. Met 6. Phe 7. Thr 8. Trp 9. Val 10. They cannot be synthesized from other amino acids or dietary sources.
