Aplicação

L-Cystine has been used in in vitro cystine solubility assay to identify potential drugs that influence cystine solubility. It is also used as a supplement of phosphate-buffered saline to slice and wash periprosthetic tissues.

Ações bioquímicas/fisiológicas

Cysteine is the source of disulfide linkages in proteins and has a role in sulfur transport. It undergoes rapid oxidation to form cystine at physiological pH. L-cystine is crucial for oxygen production and low density lipoprotein modification by arterial smooth muscle cells. It also has a role in the synthesis of glutathione.

Protein action in nature is generally controlled by the amount of protein produced and by chemical modification of the protein, and both are often perturbed in cancer. The amino acid side chains and the peptide and disulphide bonds that bind...
