Methanethiol is associated with hepatic failure in humans and the synergistic action of methanethiol, ammonia and octanoate is sufficient to account for the coma of experimental hepatic necrosis. The sulfur atom of methanethiol is eliminated from the body as urinary sulfate at a rate which is
In normal rats in a coma induced by NH+4 alone or by methanethiol alone, the brain and blood levels of ammonia or methanethiol are much higher than those observed in rats in experimental hepatic coma. When various smaller dosage combinations of NH+4, methanethiol, and octanoic acid were injected
After massive liver injury with acetaminophen, subcoma doses of hepatic failure toxins (NH+4, dimethyl disulfide [----methanethiol], octanoic acid) depressed liver thymidine kinase (TK) activity by 78%, 85%, and 90%, respectively, and ornithine decarboxylase (ODC) activity by 40%, 83%, and 78%,
Zn(II) is used in nature as a biocatalyst in hundreds of enzymes, and the structure and dynamics of its catalytic activity are subjects of considerable interest. Many of the Zn(II)-based enzymes are classified as hydrolytic enzymes, in which the Lewis acidic Zn(II) center facilitates proton
Selenium-binding protein 1 (SELENBP1) has recently been reported to catalyse the oxidation of methanethiol, an organosulfur compound produced by gut microbiota. Two of the reaction products of methanethiol oxidation, hydrogen peroxide and hydrogen sulphide, serve as signalling molecules for cell
