Application

Cholesteryl arachidoante was oxidized and used to study the biological effects.

Actions biochimiques/physiologiques

Cholesteryl arachidonate is a 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.

Notes préparatoires

Cholesteryl arachidonate is a clear, colorless viscous liquid in chloroform.

Articles

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.
