Notes: L-Cysteine-15N-d3 is intended for use as an internal standard for the quantification of L-cysteine (Item No. 33309) by GC- or LC-MS. L-Cysteine is a conditionally essential amino acid.{57614,57615} It is produced from L-methionine through the transsulfuration pathway.{57614} L-Cysteine can also be derived from dietary sources and protein turnover. It is a precursor in the biosynthesis of the intracellular antioxidant glutathione (GSH; Item No. 10007461). L-Cysteine supplementation increases GSH levels as well as decreases oxidative stress and pro-inflammatory cytokine levels in various rat and porcine disease models, including type 2 diabetes, aging, and inflammatory bowel disease (IBD). It is also an excitotoxin, inducing neuronal damage by overactivation of NMDA receptors.{57615}
