Methionine Metabolism in Developing Neural Tissue,ivities of enzymes involved, concentrations of intermediates and end-products, and changes in the overall use of the carbon skeleton of the methionine molecule. This article will describe and discuss these changes in developing neural tissue, and compare and contrast them to those taking place in li

Although the chemical structure of this thioether was elucidated in 1924., its biological role as product of methionine metabolism was demonstrated by Schlenk in 1952., even before the discovery of its precursor Ado-Met..

Cysteine Dioxygenase of Rat Liver: Some Properties and its Significance on Cysteine Metabolism of Ras a key intermediate of cysteine metabolism to hypotaurine, taurine, isethionic acid, pyruvate and sulfate in mammalian tissues.. Recently, rat liver supernatant has been shown to contain an enzyme catalyzing the oxidation of cysteine to CSA.. The enzyme responsible for the catalysis was shown to d

On analysis of the seminal vesicles of the guinea pig. an unknown amino acid peak appeared just before taurine on slight adjustment of the pH of the elution buffer. T
