The hydroxyl group (-OH) in cholesterol is aligned with the phosphate head of the phospholipid on the cell membrane, which the rest of the cholesterol goes with the fatty acid of … Triglycerides: A molecule containing three molecules of fatty acids and one molecule of glycerol (a sugar). Cholest-5-ene-3beta,25-diol At the molecular level, cholesterol possesses a slick and rigid structure. Lipid - Lipid - Cholesterol and its derivatives: Cholesterol may be the most intensely studied small molecule of biological origin. It is an essential component of cell membranes, and is the precursor for the synthesis of several important molecules. There are eight chiral centres in cholesterol. Cholesterol: A type of fat made by the liver. (Adapted from en.wikipedia.org) Remember that bond-line structures don't show the hydrogen atoms that are attached to carbon. Cholesterol contains 27 carbon atoms arranged into four fused rings and a hydrocarbon tail. Introduction to Cholesterol Metabolism. The 2D chemical structure image of cholesterol is also called skeletal formula, which is the standard notation for organic molecules. The only hydrophilic group you have on the molecule is the hydroxyl group on ring 1 Cholestereol is a hydrophobic (non-polar) compound basically because of its ring structure and the hydrocarbon chain on C-5 ring. The molecule is extremely hydrophobic. There is no internal plane of symmetry, so every carbon atom is different. > The structure of cholesterol with its numbering is shown below. At the molecular level, cholesterol possesses a slick and rigid structure. 5-Cholestene-3beta,25-diol. Cholesterol is referred to as an amphipathic molecule, that it contains its hydrophilic and hydrophobic parts. Lipoproteins: A round structure containing cholesterol and triglycerides on the inside, surrounded by a protein coat on the outside. The structure of cholesterol has three main regions; the hydrocarbon chain, the ring structure with four rings and the characteristic hydroxyl group. Cholesterol structure. Due to the presence of the hydrophilic hydroxyl group and the hydrophobic hydrocarbon region cholesterol is termed as an amphipatic molecule. Cholesterol is an extremely important biological molecule that has roles in membrane structure as well as being a precursor for the synthesis of the steroid hormones, the bile acids, and vitamin D.Both dietary cholesterol, and that synthesized de novo, are transported through the circulation in lipoprotein particles.
