title: Evidence for stereospecific phospholipid-cholesterol interaction in lipid bilayers.
abstract: The CH2 proton NMR linewidths of sn-3 and sn-1 dipalmitoyl phosphatidylcholine respond differently to the addition of cholesterol to the lipid vesicles. This result points to a stereospecific phospholipid-cholesterol interaction in the "hydrogen belt" region.
