Definition:A non-proteinogenic amino acid derivative resulting from reaction of homocysteine at the amino group, the carboxy group, or the side-chain amino group, or from the replacement of any hydrogen of homocysteine by a heteroatom. The definition normally excludes peptides containing homocysteine residues.
Synonyms:related_synonym: homocysteine derivatives
