Composition of myelin

The main constituents of myelin are the lipids (70 per cent of its dry weight), the remainder being proteins (30 per cent of its dry weight), which are largely specific to myelin, with subtle differences between PNS and CNS (Figure 8.7). The lipids provide myelin with its insulating properties, whereas the proteins serve to fuse and stabilize myelin lamellae and to mediate membrane-membrane interactions between the myelin lamellae, and between the axon and myelin sheath. Our understanding of their functions comes from studies of their localization and studies in naturally occurring mutations and genetically altered animals.
