Membrane surface orientation and motion of glycolipids: 2H NMR investigations
By means of measured quadrupole splittings, dipole-dipole couplings, and lineshape analysis, the degree of motional restriction (ordering) and bilayer orientation of gl colipid head groups can be calculated. and from a variety of r lax time measurements, insight into the rates of motion (10 -10 ''iop) s- of he arbohydrate species can be gained. visualized by means of a solid state two-dimensional 'H nmr technique. From the dependence of the 'H nmr lineshape on multipulse
