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.
