摘要：
1. Fatty acid composition of five main phospholipids of vertebrate brain myelin and synaptosomal proteolipids and membranes was studied. 2. Higher content of monoenoic and lower content of saturated and polyenoic fatty acids was found to be characteristic of phospholipids from myelin and myelin proteolipids as compared to phospholipids from synaptosomal proteolipids and membranes of vertebrates (from fishes to mammalians). Fatty acid composition of phospholipids of proteolipid complexes and of the membranes, from which they were isolated, were found to be similar in various species studied. 3. Microviscosity was found to be higher in myelin as compared to synaptosomal membranes of frog Rana temporaria and in rabbit Lepus cuniculus. It appears to be due to the difference in proteolipid content and in lipid composition of myelin and synaptosomal membranes.
