Phospholipid composition and phospholipid asymmetry of ram spermatozoa plasma membranes.

V T Hinkovska, G P Dimitrov, K S Koumanov.   

Abstract

The phospholipid composition of ram spermatozoa plasma membranes has been investigated. An exclusively high participation of the choline- and ethanolamine-plasmalogens in the phosphatidylcholine and phosphatidylethanolamine fractions has been established. Phosphatidylcholine of ram spermatozoa plasma membranes contains a great amount of polyunsaturated fatty acids. The phospholipid distribution in spermatozoa plasma membrane was investigated. It was established that the choline containing phospholipids are situated mainly in the outer membrane lipid monolayer, whereas diphosphatidylglycerol and phosphatidylserine are localized predominantly in the inner monolayer. The rest of the phospholipids are evenly distributed among the two monolayers. Ram spermal plasma membranes exhibit high phospholipase A2 activity.
