GLOSSARY & ABBREVIATIONS

Homocys

L-Homocysteinyl (L-╬▒-Amino-╬│-mercaptobutyryl)

back to overview

L-Homocysteine, the homolog of cysteine, also abbreviated Hcy, is generated by demethylation of methionine. Elevated Hcy levels in blood are a risk factor for cardiovascular and neurodegenerative diseases.
Contrary to Cys derivatives, Hcy derivatives do not tend to racemize during coupling nor to β-elimination.
