What is the function of Structure E? (Cholesterol)

Clathrin is a protein that plays a major role in the formation of coated vesicles. Clathrin was first isolated and named by Barbara Pearse in 1976. It forms a triskelion shape composed of three clathrin heavy chains and three light chains. When the triskelia interact they form a polyhedral lattice that surrounds …

Cholesterol is essential for all animal life with each cell capable of synthesizing it by way of a complex 37-step process. This begins with the mevalonate or HMG-CoA reductase pathway the target of statin drugs which encompasses the first 18 steps. This is followed by 19 additional steps to convert the resulting lanosterol into cholesterol. A human male weighing 68 kg (150 lb) normally synthesizes about 1 gram (1 000 mg) of cholesterol pe…

Apolipoprotein E (apoE) plays an important role in the transport and uptake of cholesterol by way of its high affinity interaction with lipoprotein receptors including the low-density lipo protein (LDL) receptor. ApoE is the major lipoprotein in the central nervous system.

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 hydrophobicity. Esters are formed by replacing at least one –OH (hydroxyl) group with an –O–alkyl (alkoxy) group.

The function of this isoform is in fat absorption of the small intestine and is involved in the synthesis assembly and secretion of chylomicrons. These chylomicrons transport dietary lipids to tissues while the remaining chylomicrons along with associated residual lipids are in 2–3 hours taken up by the liver via the interaction of apolipoprotein E (ApoE) with lipoprotein receptors.

From Wikipedia the free encyclopedia Cholesteryl ester transfer protein (CETP) also called plasma lipid transfer protein is a plasma protein that facilitates the transport of cholesteryl esters and triglycerides between the lipoprotei…
