The Composition of Biological Membranes
Archives of Internal Medicine, 1972The main components of biological membranes are proteins, lipids, and carbohydrates in variable proportions. Carbohydrates account for less than 10% of the mass of most membranes and are generally bound either to the lipid or protein components. Myelin has few functions and is made up almost entirely of lipids.

The Composition of Nervous Membranes
1968Publisher Summary This chapter discusses the four groups of compounds that occur mainly in nervous system and all of them are membrane constituents. These compounds are gangliosides, proteolipids, polyphosphoinositides and neurokeratin. Gangliosides are neuronal components; proteolipids, poly-phosphoinositides and neurokeratin are myelin components ...
