Physiological processes in biosynthesis (anabolism) and degradation (catabolism) of LIPIDS.

Sum of chemical changes that occur within the tissues of an organism consisting of anabolism (biosynthesis) and catabolism of lipids; the buildup and breakdown of lipids for utilization by the organism.

(lipid metabolic process) Anabolic and catabolic biochemical changes to lipids within a cell as materials needed for important life processes.

(lipid metabolic process) The chemical reactions and pathways involving lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent. Includes fatty acids; neutral fats, other fatty-acid esters, and soaps; long-chain (fatty) alcohols and waxes; sphingoids and other long-chain bases; glycolipids, phospholipids and sphingolipids; and carotenes, polyprenols, sterols, terpenes and other isoprenoids.

Lipids are fats that are either absorbed from food or synthesized by the liver. Triglycerides (TGs) and cholesterol contribute most to disease, although all lipids are physiologically important.
