DescriptionD-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. D-Cysteine exists in all living species, ranging from bacteria to plants to humans. Based on a literature review a small amount of articles have been published on D-Cysteine.
