Many bioactive compounds are derived from amino acids. This compound, found in trace amounts in mammalian brains and hypothesized to play a role as a neuromodulator or neurotransmitter, is derived from an amino acid through removal of the backbone carboxylic acid group. The amino acid from which it is derived must be: (Write out the entire name; Spelling matters, but case does not; Do not include L- or D- in the name; For acidic amino acids write the full name, e.g. “so-and-so acid”)
