L-CYSTATHIONINE Chemical Properties,Uses,Production

Chemical Properties

White Crystalline Solid

Uses

Intermediate in transsulfuration whereby the mammal transfers the sulfur of methionine via homocysteine to cysteine

Purification Methods

S,S-Cystathionine is purified by converting it to the HCl salt in 20% HCl and carefully basifying with aqueous NH3 until separation is complete. Filter it off and dry it in a vacuum. It forms prisms from H2O. The dibenzoyl derivative has m 229o (from EtOH). [IR: Greenstein & Winitz Chemistry of the Amino Acids (J Wiley) Vol 3 p2690 1961 and Tallan et al.
