Which class of glycolipids is primarily found in nerve cell membranes?
Nervous system membranes exhibit extreme glycolipid specialization essential for excitability myelination and axonal growth. Gangliosides defined by sialylated oligosaccharide linked to ceramide account up to ten mole percent lipid cerebral gray matter highest concentration among tissues localized neuronal plasma membrane growth cones synaptic terminals paranodal loops where they regulate calcium via PMCA modulation and axon myelin interaction via myelin associated glycoprotein MAG siglec four binding stabilizing axon ensheathment. Species GM1 GD1a GD1b GT1b each carry one to three N acetylneu
