GLOSSARY & ABBREVIATIONS

Orn

L-Ornithyl ((S)-2,5-Diaminopentanoyl)

back to overview

L-Ornithine (Orn) is generated from Arg during the urea cycle, but it can also be observed as an Arg degradation product in peptides. Orn formation via acylation of the Arg guanidino moiety is a well-known side-reaction in peptide synthesis.
