Application

Cholesteryl linoleate was cosonicated with cholesterol to prepare dispersions were prepared to study the cholesterol to phospholipid ratio in red blood cell membrane. It was used as HPLC standard in the analysis of rat liver lipoproteins.

Actions biochimiques/physiologiques

Cholesteryl linoleate is a major cholesterol ester found associated with the neutral core of low density lipoprotein. Receptor-LDL complexes are taken up by lysosomes and hydrolyzed to release cholesterol from the esters. The enzyme acid cholesteryl ester hydrolase is responsible for the hydrolysis of cholesteryl esters; a defective enzyme can result in the formation of atherosclerotic lesions in humans.
The most abundant cholesteryl ester in low density lipoprotein (LDL).

To test whether high-density lipoproteins (HDL) could aid in the removal in vivo of potentially atherogenic oxidized lipids, we perfused rat liver in situ with buffer supplemented with isolated human HDL containing small amounts of cholesteryl linoleate hydro(pero)xides [CH18:2-O(O)H]. Perfusion

Cholesteryl ester hydroperoxide (CE-OOH) and phosphatidylcholine hydroperoxide (PC-OOH) are the major primary oxidation products of lipoproteins. CE-OOH is present in human and rat plasmas while PC-OOH is undetectable. This is likely due to the enzymatic (plasma glutathione peroxidase) and the

Cholesterol Esterification

Cholesterol undergoes esterification to improve transport. Cholesterol esters are more easily packaged into the interior of lipoproteins - increasing the quantity that can be readily transported in the blood stream.
