Unsaturated fatty acids are Beta-oxidized in the normal pathway as far as possible. However, polyunsaturation or unsaturation at odd positions produces a molecule that the major pathways cannot utilize as a substrate. To solve this problem, a number of enzymes exist in the peroxisome to convert these molecules to appropriate substrates which can be shuttled into the normal pathway. Peroxisomes are capable of oxidizing a variety of substrates including polyunsaturated Enoyl-CoA esters. The Beta-Oxidation of unsaturated En...
