Description
- Application: L-Cystine has been used to prepare stock solution which in turn is utilized for determining the L-cysteine and L-cystine in pharmaceutical preparations as well as in urine samples by using spectrofluorimetric flow injection method.[1]
- Biochem/physiol Actions: Cystine is required for the synthesis of glutathione that protects the cells from oxidative stress. A specific x(c)-cysteine/glutamate antiporter mediates cellular uptake of cysteine in exchange for glutamate.[2] Inhibition of cysteine uptake induces toxicity in neuronal cells.[3]
- Other Notes: Preparation of N,N′-dibenzoyl-L-cystine, an efficient auxiliary for enantioselective reductions of ketones[4][5]
