| | D-Cystine Usage And Synthesis |
| Description | D-cystine is a thiol-containing non-essential amino acid that is oxidized to form CYSTINE. | | Chemical Properties | White crystals | | Uses | D-Cystine increases the rate of fertilization of mouse oocytes. | | Definition | ChEBI: The D-enantiomer of cystine. | | Biological Functions | D-Cystine functions as an antioxidant and protects tissues against radiation and pollution, slowing the aging process. It also aids protein synthesis. Cystine is abundant in many proteins of skeletal tissues and skin, and found in insulin and digestive enzymes chromotrypsinogen A, papain, and trypsinogen.
