Application

Cholesteryl arachidoante was oxidized and used to study the biological effects.[1][2]

Biochem/physiol Actions

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.[3] 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.[4]

Preparation Note

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

Acetylated low density lipoprotein inhibits the incorporation of arachidonic acid in phospholipids with a concomitant increase of cholesterol arachidonate in rat peritoneal macrophages.

C Pollaud et al.

Biochimica et biophysica acta, 1259(3), 211-219 (1995-12-07)

The aim of our work was to evaluate the influence of native low density lipoproteins (LDL) and LDL chemically modified by acetylation (acLDL) on incorporation and release of arachidonic acid (AA) in rat peritoneal macrophages. Compared to a control group

Sterol and steryl ester regulation of phospholipase A2 from the mosquito parasite Lagenidium giganteum.

J L Kerwin et al.

Lipids, 31(11), 1179-1188 (1996-11-01)

Lagenidium giganteum, a facultative parasite of mosquito larvae, cannot synthesize sterols, and requires an exogenous source of these lipids in order to enter its reproductive cycle. This parasite grows vegetatively in the absence of sterols, but requires cholesterol or structurally

[Serum cholesterol ester level in patients with ischemic heart disease and liver disease].

N P Odushko et al.

Kardiologiia, 24(10), 90-93 (1984-10-01)

The blood serum of coronary and liver patients was shown to display a similar increase in the relative levels of cholesterololeate and a some what less marked elevation in the content of cholesterol esters with saturated fatty acids. The cholesterollinoleate

Specificity of the ferrous oxidation of xylenol orange assay: analysis of autoxidation products of cholesteryl arachidonate.

Huiyong Yin et al.

Analytical biochemistry, 313(2), 319-326 (2003-02-28)

Autoxidation of polyunsaturated fatty acids and esters leads to a complex mixture containing hydroperoxides and cyclic peroxides. The oxidation mixture of cholesteryl arachidonate, which has been characterized by a variety of mass spectrometry techniques, was subject to analysis by conventional
