Lipids are large, water-insoluble molecules that have a variety of biological functions, including storing energy and serving as components of cellular membranes and lipoproteins.Cells that line the small intestine absorb dietary lipids and process them into lipoprotein particles that enter the circulation via the lymphatic system for eventual uptake by the liver. Lipid is the common word used to describe fats, oils, waxes and other related compounds. Lipid metabolism during fasting Mobilization of lipid stores adipose tissue activation of HSL: TAG → glycerol + 3 NEFA albumin liver gluconeogenesis ketone bodies (for brain, muscles) (for brain) depletion of glycogen muscle proteins → AA TCA cycle intermediates acetylCoA excess (oxaloacetate) are used for gluconeogenesis . Fatty acid synthesis and breakdown. 20.15 for the synthetic pathway). The key regulatory targets of these feedback mechanisms are 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase in cholesterol biosynthesis, the low-density lipoprotein (LDL) receptor in cholesterol uptake, and cholesterol 7α-hydroxy-lase in cholesterol catabolism.

Cholesterol is a waxy lipophilic compound of the sterol family, which contains 3 six-membered rings, a five-membered ring, and a hydroxyalcohol (Figure 26-1).That cholesterol is a critical component of normal physiological function can easily be demonstrated when its biosynthesis is disrupted or when it accumulates in excess of normal physiological requirements (see Clinical Box 26-1 and 26-2).
