L-Cysteine-15N-d3 is intended for use as an internal standard for the quantification of L-cysteine by GC- or LC-MS. L-Cysteine is a conditionally essential amino acid.1,2 It is produced from L-methionine through the transsulfuration pathway.1 L-Cysteine can also be derived from dietary sources and protein turnover. It is a precursor in the biosynthesis of the intracellular antioxidant glutathione . 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.2
