Application

L-Cystine has been used as a supplement in astroglial-conditioned media to culture cerebral astroglia. It has been used in several techniques, such as HPLC-FD, UHPLC-UV, UHPLC-MS, and triple quadrupole tandem mass spectrometry (UHPLC-MS/MS), to differentiate BMAA (β-N-methylamino-L-alanine), the cyanobacterial neurotoxin, from other diamino acids.
L-Cystine has been used as a supplement in oocyte culture media to improve oocyte maturation and parthenogenesis of embryonic development.

Biochem/physiol Actions

Cystinuria is characterized with renal transport and excretion of L-Cystine. Cysteine is one of the functional amino acids that are associated with growth, reproduction, maintenance and immunity. Cysteine is a source of disulfide linkage in protein and is associated with sulfur transport. At physiological pH, cysteine undergoes rapid oxidation to form cystine. Reduced availability of cysteine or cystine, influences leukocyte metabolism. L-Cystine is necessary for oxygen production and LDL (low density lipoprotein) modification by arterial smooth muscle cells.
