Background:

Cystathionine-d4is intended for use as an internal standard for the quantification of cystathionine by GC- or LC-MS. Cystathionine is an intermediate in the biosynthesis of cysteine that is composed of homocysteine and serine.1,2It has four potential isomers, L-cystathionine, D-cystathionine, L-allocystathionine, and D-allocystathionine.3Dietary administration of L-allocystathionine (0.74%) or the naturally occurring L-cystathionine (0.74%) substitute for cystine and increase the body weight of growing rats.
