Chemical Properties

white to off-white powder

Uses

Cystine is a nonessential amino acid that acts as a nutrient and dietary supplement. It is very slightly soluble in water and in alcohol. it improves the biological quality of the total protein in foods containing naturally occurring intact protein.

Definition

cystine: A molecule resulting fromthe oxidation reaction between thesulphydryl (-SH) groups of two cysteine molecules .This often occurs between adjacentcysteine residues in polypeptides.The resultant disulphide bridges(-S-S-) are important in stabilizingthe structure of protein molecules.

Definition

ChEBI: A sulfur-containing amino acid obtained by the oxidation of two cysteine molecules which are then linked via a disulfide bond.
