Effect of calcium on the dynamic behavior of sialylglycerolipids and phospholipids in mixed model membranes. A 2H and 31P NMR study.

DTSL, a sialic acid bearing glyceroglycolipid, has been deuteriated at the C3 position of the sialic acid headgroup and at the C3 position of the glycerol backbone. The glycolipid was studied as a neat dispersion and in multilamellar dispersions of DMPC (at a concentration of 5-10 mol % relative to phospholipid), using 2H and 31P NMR. The quadrupolar… CONTINUE READING
