  2. Cholesteryl ester - Wikipedia

    en.wikipedia.org/wiki/Cholesteryl_ester

    Cholesterol oleate, a member of the cholesteryl ester family. 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 ...

  3. Cholesterol - Wikipedia

    en.wikipedia.org/wiki/Cholesterol

    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 [citation needed] and is an essential structural and signaling component of animal cell membranes.

  4. High-density lipoprotein - Wikipedia

    en.wikipedia.org/wiki/High-density_lipoprotein

    The remainder of the serum cholesterol after subtracting the HDL is the non-HDL cholesterol. The concentration of these other components, which may cause atheroma , is known as the non-HDL-C . This is now preferred to LDL-C as a secondary marker as it has been shown to be a better predictor and it is more easily calculated.

  5. Lipoprotein - Wikipedia

    en.wikipedia.org/wiki/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 other extracellular fluids.

  6. Lecithin–cholesterol acyltransferase - Wikipedia

    en.wikipedia.org/wiki/Lecithin–cholesterol...

    Lecithin–cholesterol acyltransferase (LCAT, also called phosphatidylcholine–sterol O-acyltransferase) is an enzyme found in many animals, including humans. It converts free cholesterol into cholesteryl ester , a more hydrophobic form of cholesterol.

  7. Blood lipids - Wikipedia

    en.wikipedia.org/wiki/Blood_lipids

    Blood lipids (or blood fats) are lipids in the blood, either free or bound to other molecules. They are mostly transported in a phospholipid capsule, and the type of protein embedded in this outer shell determines the fate of the particle and its influence on metabolism. Examples of these lipids include cholesterol and triglycerides.

  8. Saponifiable lipid - Wikipedia

    en.wikipedia.org/wiki/Saponifiable_lipid

    The primary saponifiable lipids are free fatty acids, neutral glycerolipids, glycerophospholipids, sphingolipids, and glycolipids. [1] By comparison, the non-saponifiable class of lipids is made up of terpenes, including fat-soluble A and E vitamins, and certain steroids, such as cholesterol. [2]

  9. Lipid profile - Wikipedia

    en.wikipedia.org/wiki/Lipid_profile

    Total cholesterol is measured using a mixture of enzymes. First an esterase converts cholesterol esters into cholesterol and free fatty acid. Then an oxidase oxidizes the cholesterol, producing a H 2 O 2 side-product that changes the color of a dye. The amount of oxidation can be precisely quantified by light absorbance at 500 nm.
