General description

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

application

Yeast Extract Polar has been used as a component of liposome for proteoliposomes preparation.

Biochem/physiol Actions

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

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
