interactions of lipids and proteins in isolated rat intestinal microvillus membranes were examined by studying the temperature dependence of enzyme activities and of d-glucose transport in relation to the membrane lipid thermotropic transition observed by fluorescence polarization ( 26 +/- 2 degrees c ) and differential scanning calorimetry ( 23 -- 39 degrees c ) .
