Common NameS-Propylcysteine sulphoxide
DescriptionS-propylcysteine sulphoxide, also known as pcso, 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-propylcysteine sulphoxide is soluble (in water) and a moderately acidic compound (based on its pKa). S-propylcysteine sulphoxide can be found in soft-necked garlic, which makes S-propylcysteine sulphoxide a potential biomarker for the consumption of this food product.
