Metabolite Identification
Common NameD-Cysteine
DescriptionD-cysteine is an optically active form of cysteine having D-configuration. It is a cysteine and a D-alpha-amino acid. It is a conjugate base of a D-cysteinium. It is a conjugate acid of a D-cysteinate(1-). It is an enantiomer of a L-cysteine. It is a tautomer of a D-cysteine zwitterion. D-Cysteine, also known as D-cystein or DCY, belongs to the class of organic compounds known as cysteine and derivatives. Cysteine and derivatives are compounds containing cysteine or a derivative thereof resulting from reaction of cysteine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. It is a non-proteogenic sulfur-containing amino acid. D-Cysteine is known to be toxic to bacteria and several bacteria (and plants) have developed and enzyme called D-cysteine desulfhydrase (EC4.1.99.4). D-cysteine can be generated from D-Cysteine via cysteine racemase. D-Cysteine is a naturally occurring enantiomer of L-Cysteine. Cysteine is named after cystine, which comes from the Greek word kustis meaning bladder -cystine was first isolated from kidney stones. D-Cysteine exists in all living species, ranging from bacteria to humans. Outside of the human body, D-Cysteine has been detected, but not quantified in several different foods, such as chervils, fruits, lichee, nuts, and cherimoya.
