| Name | D-Cysteine |
|---|
| Description | Cysteine (abbreviated as Cys or C) is an alpha-amino acid. The L-isomer is one of the 22 proteinogenic amino acids, i.e., the building blocks of proteins. D-isomers are used as carbon, nitrogen, and energy source. Cysteine is unique among the twenty common amino acids because it contains a thiol group. [YMDB]. D-Cysteine is found in many foods, some of which are red raspberry, muscadine grape, pigeon pea, and groundcherry. |
