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.
Biochem/physiol Actions
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.

In eukaryotic protein N-glycosylation, a series of glycosyltransferases catalyse the biosynthesis of a dolichylpyrophosphate-linked oligosaccharide before its transfer onto acceptor proteins1. The final seven steps occur in the lumen of the endoplasmic reticulum (ER) and require dolichylphosphate-activated mannose and glucose
