Metabolic defects of fatty acid oxidation

When β oxidation is defective because of either mutation or deficiency in carnitine, the ω (omega) oxidation of fatty acids becomes more important in mammals. The ω oxidation of fatty acids is another pathway for F-A degradation in some species of vertebrates and mammals that occurs in the endoplasmic reticulum of the liver and kidney, it is the oxidation of the ω carbon—the carbon farthest from the carboxyl group (in contrast to β {\displaystyle \beta } oxidation which occurs at the carboxyl end of fatty acid, in the mitochondria).
