This page describes the biosynthesis of triglycerides and phospholipids in mammals. It is not intended to be an exhaustive list, but concentrates on major categories with established physiological importance. Separate pages hold information on lipid degradation, isoprene and steroid biosynthesis. The transport of lipid precursors from mitochondria to cytosol is considered in the page on the integration of metabolism. Click here to skip over the detailed contents section.
