L-ETHIONINE Chemical Properties,Usage,Production

Chemical Properties

White Solid

Uses

Ethionine-induced inhibition of protein synthesis and lowering of ATP level in the liver.

Definition

ChEBI: An S-ethylhomocysteine that has S-configuration at the chiral centre.

Purification Methods

Likely impurities are N-acetyl-(R and S)-ethionine, S-methionine, and R-ethionine. Crystallise it from water by adding 4volumes of EtOH or 85% aqueous EtOH. It sublimes at 196-216o/0.3mm with 99.1% recovery and unracemised [Gross & Gradsky J Am Chem Soc 77 1678 1955]. [Weiss & Stekol J Am Chem Soc 73 2399 1951, Greenstein & Winitz The Chemistry of the Amino Acids J. Wiley, Vol 3 pp 2658, 2659 1961, Beilstein 4 IV 3194.]
