The enantiomers of a homologous series (C6-C10) of 2-mercapto-4-alkanones were obtained by lipase-catalyzed kinetic resolution of the corresponding racemic 2-acetylthio-4-alkanones. Their configurations were assigned via vibrational circular dichroism and 1H NMR anisotropy based methods. Odor thresholds and odor qualities were

Two alternative metabolic pathways, acyl glucuronidation and acyl-CoA formation, are implicated in the generation of reactive acylating metabolites of carboxylic acids. Here, we describe studies that determine the relative importance of these two pathways in the metabolic activation of a

Optical isomerization of 2-phenylpropionic acid (hydratropic acid, HTA) was studied in the organs of male rat in vitro. (R)-(-)-HTA was not isomerized by rat liver homogenate even after the addition of CoA, ATP, and Mg2+ to the incubation mixture; however
