GLOSSARY & ABBREVIATIONS

Homoarg
L-Homoarginyl (L-α-Amino-ε-guanidinohexanoyl)
L-Homoarginine, the homolog of L-arginine, also abbreviated Har, can be found in plasma and urine. Homoarginine results from the guanidination of Lys, which can also be performed on peptides and proteins.
Activated Har derivatives show a far lower tendency for lactamization than the corresponding Arg derivatives.
