The activation energy (Ea) for cholesterol exchange between dioleoyl phosphatidylcholine vesicles and erythrocyte 'ghosts' is measured as a function of molar percentage of cholesterol in both donor and acceptor membranes. A sharp increase in Ea occurs (from 39.9kJ/mol to 84kJ/mol) when the molar percentage of cholesterol decreases from 30 to 20%.
测定了二油酰磷脂酰胆碱囊泡与红细胞“血影”之间胆固醇交换的活化能(Ea),它是供体膜和受体膜中胆固醇摩尔百分比的函数。当胆固醇的摩尔百分比从30%降至20%时,Ea会急剧增加(从39.9kJ/mol增至84kJ/mol)。
