Cholesteryl esters are a type of dietary lipid and are ester derivatives of cholesterol. The ester bond is formed between the carboxylate group of a fatty acid and the hydroxyl group of cholesterol. Cholesteryl esters have a lower solubility in water due to their increased hydrophobicity. Esters are formed by replacing at least one –OH ...
Cholesteryl ester transfer protein (CETP), also called plasma lipid transfer protein, is a plasma protein that facilitates the transport of cholesteryl esters and triglycerides between the lipoproteins. It collects triglycerides from very-low-density (VLDL) or Chylomicrons and exchanges them for cholesteryl esters from high-density lipoproteins ...
Cholesterol is the principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils. [3] [4] Cholesterol is biosynthesized by all animal cells and is an essential structural component of animal cell membranes. In vertebrates, hepatic cells typically produce the greatest amounts.
Structure of a chylomicron (the largest lipoprotein). ApoA , ApoB , ApoC , ApoE are apolipoproteins ; green particles are phospholipids ; T is triglyceride ; C is cholesterol ester . A lipoprotein is a biochemical assembly whose primary function is to transport hydrophobic lipid (also known as fat ) molecules in water, as in blood plasma or ...
Cholesteryl benzoate, also called 5-cholesten-3-yl benzoate, is an organic chemical, an ester of cholesterol and benzoic acid. It is a liquid crystal material forming cholesteric liquid crystals with helical structure. It can be used with cholesteryl nonanoate and cholesteryl oleyl carbonate in some thermochromic liquid crystals.
Stanol esters is a heterogeneous group of chemical compounds known to reduce the level of low-density lipoprotein (LDL) cholesterol in blood when ingested, [1] though to a much lesser degree than prescription drugs such as statins. [2] The starting material is phytosterols from plants.
Lecithin–cholesterol acyltransferase (LCAT, also called phosphatidylcholine–sterol O-acyltransferase) is an enzyme, in many animals including humans, that converts free cholesterol into cholesteryl ester (a more hydrophobic form of cholesterol), which is then sequestered into the core of a lipoprotein particle, eventually making the newly synthesized HDL spherical and forcing the reaction ...
Cholesterol sulfate. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Cholesterol sulfate, or cholest-5-en-3β-ol sulfate, is an endogenous steroid and the C3β sulfate ester of cholesterol. [1][2] It is formed from cholesterol by steroid sulfotransferases (SSTs) such as SULT2B1b ...
