| Toxicity | The Sethyl analog of methionine. It is a carcinogen and hepatotoxic agent once proposed as an antineoplastic agent. It inhibits the incorporation of methionine and glycine into proteins and substitutes for methionine in transmethylation reactions, the ethyl group appearing in the products in place of the methyl groups of methionine (e.g., ethylcholine is formed instead of choline). Ethionine is currently used only as an experimental compound in studies of hepatotoxicity and methionine metabolism and nutrition. | |||||||||

Chemical Properties
Off-White Solid
Uses
DL-Ethionine is used as a dietary supplement to accelerate cholangiocarcinogenesis in vivo. It is also used to induce oxidative stress in liver to study the levels and activities of anti-oxidative enzymes and compounds such as glutathione.
Definition
ChEBI: A non-proteinogenic alpha-amino acid that is methionine in which the S-methyl group is replaced by an S-ethyl group.
General Description
White crystalline flakes.
Air & Water Reactions
Slightly soluble in water.
Reactivity Profile
A synthetic thio-substituted amino acid.
Health Hazard
ACUTE/CHRONIC HAZARDS: When heated to decomposition DL-ETHIONINE emits toxic fumes of NOx and SOx.
