Description : What is alpha oxidation of fatty acid?
Last Answer : It is a process by which fatty acids are oxidised by removing carbon atoms, one at a time, from the carboxyl end. It is used for fatty acids that have a methyl group at the beta-carbon, which blocks beta-oxidation. Alpha oxidation does not generate energy.
