( l6) Pyruvic acid, condensed structural formula below, was named "Molecule of the Week" for the week ofMay 4 by the American Chemical Society. Presumably this accolade was in recognition ofthe biochemical significance of pyruvic acid, a compound formed by the anaerobic decomposition of glucose. ) J. 4. (18) (0e) (20) (18) (10) 5. complete sffuctural formula strucfural isomer lactic acid o (2) Write a complete structural formula for pyruvic acid showing all bonds, and all lone pairs. o (2) Fyruvic acid is a keto acid. Write a structure for a structural isomer of pyruvic acid. o (2) During heavy physical exercise pyruvic acid is converted to lactic acid, CiHeOr, a difunctional compound in which a hydroxyl group replaces the carbonyl group. Using any appropriate structural formula, write a structure for lactic acid.
