Description The study of metabolism requires a working familiarity with many small molecule compounds. Those of you who have learned the structures of your biomolecules will find yourselves at a huge advantage once it comes time to explain reaction mechanisms and anticipate enzymatic activities. Take this opportunity to review and/or learn your small biologically active compounds. On a separate sheet of paper, neatly draw the structures of the 20 common L-amino acids. Under each amino acid structure write the name, three-letter code, and single-letter code. On a separate sheet of paper, neatly draw the structures of each of the D-aldose triose, tetrose, pentose, and hexose sugars (there should be fifteen in all) in Fisher diagram representations. Name them. On a separate sheet of paper, neatly draw Haworth projections of, D-Glucose and D-Galactose as pyranoses in their ?-anomeric forms and D-Ribose and D-Fructose as furanoses in their ?-anomeric forms. On a separate sheet of paper, neatly draw the structures of the following fatty acids: lauric acid, myristic acid, palmitic acid, and stearic acid. On a separate sheet of paper, neatly draw the structure of glycerol. How is this different from glyceraldehyde? What type of chemical reaction (oxidation or reduction) would convert glyceraldehyde to glycerol? On a separate sheet of paper, neatly draw the structures of the following dicarboxylic acids: oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, and pimelic acid. Can you think of a mnemonic device that helps you remember the names of these dicarboxylic acid compounds in order?
