WebbOxidation reaction of alcohols. The oxidation of a primary alcohol produces an aldehyde which is further oxidized to a carboxylic acid in the presence of an oxidizing agent (KMnO 4 or K 2 Cr 2 O 7) under acidic or alkaline conditions. Webb10 apr. 2024 · Alcohol oxidases (EC 1.1.3.x) oxidise alcohols to aldehydes or ketones using O 2 as a terminal electron acceptor. The reaction produces H 2 O 2 as a side product. To avoid enzyme deactivation, H 2 O 2 is usually removed in situ by an accessory enzyme: a catalase or a peroxidase. Thus, the net reaction becomes irreversible (Scheme 5 ).
