Reverse cholesterol transport (RCT) is the pathway for removal of peripheral tissue cholesterol and involves transport of cholesterol back to liver for excretion, starting from cellular cholesterol efflux facilitated by lipid-free apolipoprotein A1 (ApoA1) or other lipidated high-density lipoprotein (HDL) particles within the interstitial space.

1.  Cholesterol (50%) is converted to bile acids (excreted in feces), serves as a precursor for the synthesis of steroid hormones, vitamin D, coprostanol & cholestanol.  The bile acids are synthesized in the liver from cholesterol.  Contain 24 carbon atoms, 2 or 3 OH groups in steroid nucleus & a side chain ending in carboxyl group.

through the skin. Cholesterol can be excreted through sweating and through the production of sex hormones (like estrogen), of which can be further oxidized and excreted in the urine. However, the major route of disposal of cholesterol is through the synthesis and excretion of bile acids and bile salts. The main route for excretion of cholesterol from the body is a. no excretion; it is all reused by the body. b.

Cholesterol is important to normal metabolism, and has been in short supply during all but the latest few generations The absorption of cholesterol by the small intestine is a major route for the net entry of cholesterol into the body and can therefore affect the plasma low density lipoprotein-cholesterol (LDL-C) concentration. These studies used ezetimibe, a potent inhibitor of cholesterol absorption, to delineate … However, some important early studies have shown that the flux of free cholesterol is at least 1 order of magnitude larger than the flux of esterified cholesterol and that the mechanism by which transport proteins mediate these fluxes may be quite different. 30,39 In rodents, in which HDL is the prominent lipoprotein class, the main route for both free cholesterol and cholesterol … Biliary secretion is generally considered to be an obligate step in the pathway of excess cholesterol excretion from the body. We have recently shown that an alternative route exists. Cholesterol Metabolism with Emphasis on Synthesis and Absorption. Human cholesterol levels are dependent on several inter-related processes: its synthesis (mainly in the liver, endocrine organs, muscle and skin), absorption from the diet and excretion into bile (see Figure 1). 2014-04-15 Cholesterol is a steroid lipid, found in the body tissues (and blood plasma) of vertebrates.

Slightly less than half of the cholesterol in the body derives from biosynthesis de novo. Biosynthesis in the liver accounts for approximately 10%, and in the intestines approximately 15%, of the amount produced each day. The cholesterol biosynthesis pathway involves enzymes that are in the cytoplasm, microsomes (ER), and peroxisomes.

Fecal excretion of sterols is stimulated upon whole body Transintestinal cholesterol efflux (TICE) provides an attractive target to increase body cholesterol excretion. At present, the cholesterol donor responsible for direct delivery of plasma N2 - Biliary secretion is generally considered to be an obligate step in the pathway of excess cholesterol excretion from the body.
