Chemical Information
FooDB NameS-sulfo-L-cysteine
DescriptionS-sulphocysteine, also known as cysteinyl-S-sulfonate or L-cysteine hydrogen sulfuric acid, is a member of the class of compounds known as S-sulfo-l-cysteines. S-sulfo-l-cysteines are s-conjugated L-cysteine where the S-substituent is specified as a sulfo group. S-sulphocysteine is soluble (in water) and an extremely strong acidic compound (based on its pKa). S-sulphocysteine can be found in a number of food items such as hazelnut, star anise, agar, and sorghum, which makes S-sulphocysteine a potential biomarker for the consumption of these food products. S-sulphocysteine can be found primarily in blood and urine. S-sulphocysteine exists in all living organisms, ranging from bacteria to humans. Moreover, S-sulphocysteine is found to be associated with sulfite oxidase deficiency and molybdenum cofactor deficiency.
