In order Propanoic acid, \(C_2H_5COOH\), is an organic acid that is a liquid at room temperature. The metabolism of propanoic acid begins with its conversion to propionyl coenzyme A (propionyl-CoA), the usual first step in the metabolism of carboxylic acids. The name carboxyl comes from the fact that a carbonyl and a hydroxyl group are attached to the same carbon. Some propionic acid is oxidized to lactic acid during absorption, but most passes to the liver, which removes nearly all of it from the portal blood. In the pure state, it is a colorless, water soluble, and corrosive liquid with a sharp, somewhat unpleasant odor. 5 degree 109. uk ) Nov 17, 2024 · -Draw Lewis structure of CH3CH2COOH (propanoic acid).
