Yeasts can convert amino acids to flavor alcohols following the Ehrlich pathway, a reaction sequence comprising transamination, decarboxylation, and reduction. The alcohols can be further derivatized to the acetate esters by alcohol acetyl transferase. Using L: -methionine as sole nitrogen

Adduct formation has been considered to be a major causal factor of DNA damage by carcinogenic heterocyclic amines. By means of experiments with 32P-labeled DNA fragments and an electrochemical detector coupled to a high-pressure liquid chromatograph, we investigated whether the

The primary flavor compound in potato, methional, is synthesized from methionine by the Strecker degradation reaction. A major problem associated with potato processing is the loss of methional. Methional or its precursor, methionine, is not added back during potato processing

Carcinogenic benzo[a]pyrene (BP) is generally considered to show genotoxicity by forming DNA adducts of its metabolite, BP-7,8-diol-9,10-epoxide. We investigated oxidative DNA damage and its sequence specificity induced by BP-7,8-dione, another metabolite of BP, using (32)P-5'-end-labeled DNA.
