Amino acids are named after two of their functional groups: the amino group (NH₂), which acts like a base, and the carboxyl group (COOH), which acts like an acid. Amino acids also
contain a third functional group, often called the R group. In alanine, the R group is a methyl group (CH₂). In serine, the R group is a methyl alcohol (-CH₂OH).
