The total lipids from yeast are useful in understanding lipid metabolism. Yeast lipids serve as model membranes for understanding the lipid raft forming mechanisms. These lipids have a potential to self-organize. The fatty acid composition of polar lipids in yeast are modulated in response to acid stress.

General description

Yeast is rich in sphingolipids. The apolar lipids from yeast separates out first during chloroform/methanol extraction. The aqueous phase contains polar lipids. A total of 162 lipids pertaining to 21 lipid classes are identified in yeast. Phosphatidylinositol comprises the major component of yeast lipid accounting to 17% to 30%.

Polar Lipid Extract is derived from the total lipid extract by precipitation with acetone followed by extraction of the acetone insoluble material with diethyl ether.
