Cholesteryl ester - Wikipedia
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 …
Cholesterol and Cholesterol Esters - structure, occurrence ...
2024年11月20日 · In the high-density lipoproteins (HDL), cholesterol esters are synthesised largely by transfer of C 18 fatty acids (18:1 and 18:2) to cholesterol from position sn-2 of phosphatidylcholine (‘lecithin’) catalysed by the enzyme lecithin:cholesterol acyl transferase (LCAT); the other product is 1‑acyl-lysophosphatidylcholine (see our web page ...

膽固醇酯（英文 Cholesterol ester）是膽固醇的酯化產物，是膽固醇的儲存形式和運輸形式。 在肝臟內膽固醇和膽固醇酯各佔50%，在 中樞神經系統 、 紅細胞 和膽汁中基本只含有膽固醇，在血漿中膽固醇酯佔總膽固醇的65%。
Cholesterol | C27H46O | CID 5997 - PubChem
Sources of cholesterol include lipoprotein uptake from serum (LDL and HDL), de novo synthesis from acetate via the acetyl coenzyme A pathway, and hydrolysis of cholesteryl ester (CE) by neutral CE hydrolase (nCEH). The storage pool in the form of lipid droplets is derived principally from the conversion of free cholesterol to CE catalyzed by ...
Crystal structure of cholesteryl ester transfer protein reveals a …
2007年1月21日 · Here we describe the structure of CETP at 2.2-Å resolution, revealing a 60-Å-long tunnel filled with two hydrophobic cholesteryl esters and plugged by an amphiphilic phosphatidylcholine at each...
Cholesterol Ester - an overview | ScienceDirect Topics
Cholesterol is transported in the bloodstream by lipoproteins, primarily in the form of cholesterol esters. Because of their hydrophobicity, cholesterol esters are more suitable for cellular storage, whereas free cholesterol acquired by cells through hydrolysis of cholesterol esters accumulates in the cell membranes as a structural component.

Cholesterol Ester (22:5n3/0:0) | C49H78O2 | CID 53480463 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.
Cholesteryl Ester - an overview | ScienceDirect Topics
The formation of cholesteryl ester from the esterification of free cholesterol and fatty acyl CoA is catalyzed by the microsomal acyl coenzyme A: cholesterol acyltransferase (ACAT). Newly synthesized cholesteryl esters accumulate within the rough ER and bud off as cytoplasmic lipid droplets; the abundance of the latter is a key feature of ...
Properties, structure, and applications of microbial sterol esterases ...
2016年1月7日 · In this review, the information available on microbial sterol esterases has been gathered, taking into account their origin, production and purification, heterologous expression, structure, stability, or substrate specificity, which are the main properties that make them attractive for different applications.
Cholesteryl stearate | C45H80O2 | CID 118246 - PubChem
Cholesteryl stearate is a cholesterol ester obtained by the formal condensation of the hydroxy group in cholesterol with the carboxy group of stearic acid. It has a role as a mouse metabolite. It is functionally related to an octadecanoic acid.
