Cholesterol exchange as a function of cholesterol/phospholipid mole ratios.

M J Poznansky, S Czekanski.   

Abstract

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%.
