[Stabilization of flat bilayer lipid membranes by cholesterol]. 1978

I A Bagaveev, and Iu G Rovin

Cholesterol is found to produce a stabilizing effect on bilayer lipid membranes (BLM) from alpha-monoglycerides of fatty acids and n-octan. The greatest stabilization effect is observed for alpha-monoglycerides, in which the length of hydrocarbon radical coincides with the length of cholesterol molecule. The life time of BLM from alpha-monolaurin, cholesterol and n-octan is measured in hours, and the tension of electric damage of the membrane reaches 860 mV.

UI	MeSH Term	Description	Entries
D008563	Membrane Lipids	Lipids, predominantly phospholipids, cholesterol and small amounts of glycolipids found in membranes including cellular and intracellular membranes. These lipids may be arranged in bilayers in the membranes with integral proteins between the layers and peripheral proteins attached to the outside. Membrane lipids are required for active transport, several enzymatic activities and membrane formation.
