WebAcetaldehyde is an industrially important solvent used as an intermediate for the synthesis of a wide range of compounds. On oxidation it forms acetic acid and ethanol on reduction. [ 1] The interaction of Criegee intermediate (CH 2 OO) with acetaldehyde has been measured. [ 2] Its effect as a neuroactive agent has been studied. [ 3] WebAbstract. Acetaldehyde, the toxic product of ethanol metabolism in the liver, covalently binds to a variety of proteins, thereby altering liver function and structure. Through its binding to tubulin, acetaldehyde decreases the polymerization of microtubules thereby impairing protein secretion and favouring their retention, with associated ...
