Metabolite Identification

Common Name

(S)C(S)S-S-Methylcysteine sulfoxide

Description

S-Methylcysteine sulfoxide belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). S-Methylcysteine sulfoxide has been detected, but not quantified in, several different foods, such as cabbages (Brassica oleracea var. capitata), garden onions (Allium cepa), soft-necked garlics (Allium sativum L. var. sativum), and white cabbages (Brassica oleracea L. var. capitata L. f. alba DC.). This could make S-methylcysteine sulfoxide a potential biomarker for the consumption of these foods. Based on a literature review a small amount of articles have been published on S-Methylcysteine sulfoxide.
