  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. Sterol O-acyltransferase - Wikipedia

    en.wikipedia.org/wiki/Sterol_O-acyltransferase

    Sterol O-acyltransferase (also called Acyl-CoA cholesterol acyltransferase, Acyl-CoA cholesterin acyltransferase [citation needed] or simply ACAT) is an intracellular protein located in the endoplasmic reticulum that forms cholesteryl esters from cholesterol.

  4. Lipoprotein - Wikipedia

    en.wikipedia.org/wiki/Lipoprotein

    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 ...

  5. Sterol esterase - Wikipedia

    en.wikipedia.org/wiki/Sterol_esterase

    The systematic name is steryl-ester acylhydrolase. Other names in common use include cholesterol esterase , cholesteryl ester synthase , triterpenol esterase , cholesteryl esterase , cholesteryl ester hydrolase , sterol ester hydrolase , cholesterol ester hydrolase , cholesterase , and acylcholesterol lipase .

  6. 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.

  7. Lecithin–cholesterol acyltransferase - Wikipedia

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

    It converts free cholesterol into cholesteryl ester, a more hydrophobic form of cholesterol. This process sequesters cholesterol ester into the core of a lipoprotein particle, eventually making the newly synthesized HDL spherical and forcing the reaction to become unidirectional since the particles are removed from the surface.

  8. Hormone-sensitive lipase - Wikipedia

    en.wikipedia.org/wiki/Hormone-sensitive_lipase

    The enzyme has a long and a short form. The long form is expressed in steroidogenic tissues such as testis, where it converts cholesteryl esters to free cholesterol for steroid hormone production. The short form is expressed in adipose tissue, among others, where it hydrolyzes stored triglycerides to free fatty acids. [8]

  9. Lipid - Wikipedia

    en.wikipedia.org/wiki/Lipid

    [2]: 328 The middle structure is a triglyceride composed of oleoyl, stearoyl, and palmitoyl chains attached to a glycerol backbone. At the bottom is the common phospholipid phosphatidylcholine . Lipids are a broad group of organic compounds which include fats , waxes , sterols , fat-soluble vitamins (such as vitamins A , D , E and K ...
