amino acids CORRECT ANSWER α-Amino-substituted carboxylic acids, the building blocks of proteins. residue CORRECT ANSWER A single unit in a polymer; for example, an amino acid in a polypeptide chain. The term reflects the fact that sugars, nucleotides, and amino acids lose a few atoms (generally the elements of water) when incorporated in their respective polymers. R group CORRECT ANSWER (1) Formally, an abbreviation denoting any alkyl group. (2) Occasionally, used in a more general sense...
