Webreflects the activity of cystathionine β-synthase and cystathionine γ-lyase. For example, it is well known that L-cystathionine is observed in the urine of cystathionuric patients owing to a cystathionine γ-lyase deficiency.6) Thus, L-cystathionine is considered to be a key amino acid related to metabolic conditions. Thus, its quantitative WebL-Cystathionine is an important metabolic intermediate in the L-cysteine transsulfuration pathway from L-methionine via L-homocysteine in mammalian tissues. 3) This pathway is active in organs such as the liver, kidneys, pancreas, and intestines. 4) L-Cystathionine is also present in brain tissue.
