Metabolite Identification

Common Name

S-Allylcysteine

Description

S-Allylcysteine belongs to the class of organic compounds known as cysteine and derivatives. Cysteine and derivatives are compounds containing cysteine or a derivative thereof resulting from reaction of cysteine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. S-Allylcysteine is a cooked and roasted tasting compound. S-Allylcysteine is found, on average, in the highest concentration within soft-necked garlics (Allium sativum L. var. sativum). S-Allylcysteine has also been detected, but not quantified in, several different foods, such as onion-family vegetables, welsh onions (Allium fistulosum), garden onion (var.), garden onions (Allium cepa), and green onion. This could make S-allylcysteine a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on S-Allylcysteine.
