Chemical Information
FooDB NameS-Methyl-L-cysteine sulfoxide
DescriptionS-methyl-l-cysteine sulfoxide, also known as methiin, (l-ala)-(R)-isomer or kale anemia factor, is a member of the class of compounds known as L-alpha-amino acids. L-alpha-amino acids are alpha amino acids which have the L-configuration of the alpha-carbon atom. S-methyl-l-cysteine sulfoxide is soluble (in water) and a moderately acidic compound (based on its pKa). S-methyl-l-cysteine sulfoxide can be found in radish and soft-necked garlic, which makes S-methyl-l-cysteine sulfoxide a potential biomarker for the consumption of these food products.
