產(chǎn)品簡(jiǎn)介』
Cholesterol - PEG - SH (Cholesterol - polyethylene glycol (PEG) - hydrophobic base) is a conjugate between polyethylene glycol (PEG) and Cholesterol content.CLS - PEG - SH cholesterol is lipid molecule, is the essential structural components of all animal cell membranes, it can keep membrane structure integrity and liquidity.
Cholesterol, also can be used as a precursor of steroid hormones and bile acid biosynthesis and many other biological functions. Functionalization of PEG lipid and lecithin can be used for protein - PEG.
PEG鏈顯著改善膽固醇的溶解度,膽固醇通常難以溶于水溶液和極性溶液中。
此外,巰基可以和其他許多基團(tuán)發(fā)生化學(xué)反應(yīng),比如:馬來酰亞胺,碘乙酰胺。巰基PEG通過上述基團(tuán)反應(yīng)可以連接到靶向底物上面膽固醇可調(diào)節(jié)磷脂雙分子層膜的流動(dòng)性,使膜通透性降低,減少滲漏。
同時(shí)并對(duì)磷脂的氧化有一定保護(hù)作用。
