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