Hypotaurine
Hypotaurine belongs to the class of organic compounds known as sulfinic acids. Sulfinic acids are compounds containing a sulfinic acid functional group, with the general structure RS(=O)OH (R = organyl, not H). Hypotaurine exists in all living species, ranging from bacteria to humans. Within humans, hypotaurine participates in a number of enzymatic reactions. In particular, hypotaurine can be biosynthesized from cysteamine; which is catalyzed by the enzyme 2-aminoethanethiol dioxygenase. In addition, hypotaurine can be biosynthesized from 3-sulfinoalanine through its interaction with the enzyme cysteine sulfinic acid decarboxylase. In humans, hypotaurine is involved in taurine and hypotaurine metabolism. [Spectral] Hypotaurine (exact mass = 109.01975) and Cytosine (exact mass = 111.04326) were not completely separated on HPLC under the present analytical conditions as described in AC$XXX. Additionally some of the peaks in this data contains dimers and other unidentified ions. Hypotaurine is a product of enzyme cysteamine dioxygenase [EC 1.13.11.19] in taurine and hypotaurine metabolism pathway (KEGG). It may function as an antioxidant and a protective agent under physiological conditions (PMID 14992269). [HMDB] Hypotaurine (2-aminoethanesulfinic acid), an intermediate in taurine biosynthesis from cysteine in astrocytes, is an endogenous inhibitory amino acid of the glycine receptor. Antioxidant[1].
