Cholesterol - polyethylene glycol (peg) - amine with very stable chemical bond/key by key or amide connect cholesterol and amine to polyethylene glycol (peg). And easy to hydrolysis of ester bond in the aqueous solution is different, between cholesterol and PEG wake key has chemical stability. Cholesterol is a membrane composition, have adjust the function of membrane fluidity, elasticity and permeability.
When proteins embedded in the membrane, it fills the other space form the accumulation of lipid species. Polyethylene glycol (peg), cholesterol, as a kind of amphiphilic lipid derivatives, can be used for the preparation of liposomes and other micelles as drug delivery system. Except the mPEG cholesterol, also can pass the custom synthesis activity or dye tag PEG cholesterol reagents, and the cycle is short.
