Cysteine S-sulfate
Cysteine-S-sulfate (SSC) is produced by reaction of inorganic sulfite and cystine by a yet unknown pathway and is a very potent NMDA-receptor agonist. Electrophysiological studies have shown that SSC displays depolarizing properties similar to glutamate. Patients affected with either Molybdenum cofactor deficiency (MOCOD, an autosomal recessive disease that leads to a combined deficiency of the enzymes sulphite oxidase, an enzyme that catalyzes the conversion of sulfite to inorganic sulfate, xanthine dehydrogenase and aldehyde oxidase) or isolated sulphite oxidase deficiency (ISOD, an extremely rare autosomal recessive disorder with identical clinical manifestations to MOCOD) excrete elevated levels of SSC. This rare disorder is associated with brain damage (seizures, spastic quadriplegia, and cerebral atrophy), mental retardation, dislocated ocular lenses, blindness, and excretion in the urine of abnormally large amounts of SSC, sulfite, and thiosulfate but no inorganic sulfate (PMID: 17764028, 15558695).

S-sulfo-L-cysteine
An S-substituted L-cysteine where the S-substituent is specified as a sulfo group. S-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.
