DL-Homocystine

2-amino-4-[(3-amino-3-carboxypropyl)disulfanyl]butanoic acid

C8H16N2O4S2 (268.0551)


Homocystine is the oxidized form of homocysteine. Homocystine is a dipeptide consisting of two homocysteine molecules joined by a disulfide bond. Homocysteine is a sulfur-containing amino acid that arises during methionine metabolism. Homocystine occurs only transiently before being reduced to homocysteine and converted to the harmless cystathionine via a vitamin B6-dependent enzyme. Homocystine and homocysteine-cysteine mixed disulfides account for >98\\\\\% of total homocysteine in plasma from healthy individuals (PMID 11592966). Homocystine has been shown to stereospecifically induce endothelial nitric oxide synthase-dependent lipid peroxidation in endothelial cells, thereby inducing a vascular cell type-specific oxidative stress. This vascular stress is associated with atherothrombotic cardiovascular disease (PMID: 14980706). High levels of homocysteine (and homocysteine) can be found in individuals suffering from homocystinura due to cystathionine synthase deficiency (PMID: 4685596) Homocystine is the double-bonded form of homocysteine, but it occurs only transiently before being converted to the harmless cystathionine via a vitamin B6-dependent enzyme. Acquisition and generation of the data is financially supported in part by CREST/JST. KEIO_ID H041 4,4'-Disulfanediylbis(2-aminobutanoic acid) is an endogenous metabolite. DL-Homocystine is the double-bonded form of homocysteine and homocysteine is recognized as an important substance in the pathogenesis and pathophysiology of schizophrenia. L-Homocystine is the oxidized member of the L-homocysteine. Homocysteine is a pro-thrombotic factor, vasodilation impairing agent, pro-inflammatory factor and endoplasmatic reticulum-stress inducer used to study cardiovascular disease mechanisms.
