Chemical Information
FooDB NameS-Propylcysteine sulfoxide
Description(r)c(r)s-s-propylcysteine sulfoxide is a member of the class of compounds known as alpha amino acids. Alpha amino acids are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon) (r)c(r)s-s-propylcysteine sulfoxide is soluble (in water) and a moderately acidic compound (based on its pKa). (r)c(r)s-s-propylcysteine sulfoxide can be found in garden onion and onion-family vegetables, which makes (r)c(r)s-s-propylcysteine sulfoxide a potential biomarker for the consumption of these food products.
