3-Mercaptolactate-cysteine disulfide
IUPAC 名称
3-{[(2R)-2-amino-2-carboxyethyl]disulfanyl}-2-hydroxypropanoic acid
描述
3-mercaptolactate-cysteine disulfide is a compound analog of cysteine excreted in the urine of patients affected by Mercaptolactate-cysteine disulfiduria (MCDU, OMIM 249650), the product of disorder of sulfur amino acid metabolism and a reduced activity of the enzyme mercaptopyruvate sulfurtransferase (MST, EC 2.8.1.2). Reduction of protein in the diet, addition of pyridoxine or of neomycin did not affect the urinary excretion of beta-mercaptolactate-cysteine disulfide of a mentally defective patient who was excreting this mixed disulfide. Addition of cysteine to the diet did increase the excretion of this disulfide (PMID: 3888441, 527218, 6945862, 5644041) [HMDB]
