An update on the pathways of polyunsaturated fatty acid metabolism.
The biosynthesis of 4, 7, 10, 13, 16-22:5 and 4, 7, 10, 13, 16, 19-22:6 from dietary linoleate and linolenate, respectively, does not totally take place in the endoplasmic reticulum but does require the participation of enzymes in the endoplasmic reticulum and peroxisomes. The absence of an endoplasmic reticulum-associated acyl-CoA-dependent delta 4 desaturase also requires the controlled movement of 22- and 24-carbon polyunsaturated fatty acids between the endoplasmic reticulum and peroxisomes.
