Phosphoglycerides structure
WebPhosphoglycerides, sphingolipids, and steroids make up the basic structure of all cell membranes. These membranes control the flow of molecules into and out of cells and allow cell-to-cell communication. [Pg.519] According to the fluid-mosaic model of membrane structure ( ), cell membranes consist of a fluid phospholipid bilayer. WebPhospholipids are one of these heterogeneous compounds included in this category of biological molecules. Phospholipids are characterized by having a phosphate group in their structure making them polar compounds. They are the most prominent lipids present in all types of membranes. Different phospholipids have different structures, properties ...

They consist of a glycerol unit with fatty acids attached to the first two carbon atoms, while a phosphoric acid unit, esterified with an alcohol molecule (usually an amino alcohol, as in part (a) of Figure 7.8 …
http://chemistry.elmhurst.edu/vchembook/553phosglycerides.html The term glycerophospholipid signifies any derivative of glycerophosphoric acid that contains at least one O-acyl, or O-alkyl, or O-alk-1'-enyl residue attached to the glycerol moiety. The phosphate group forms an ester linkage to the glycerol. The long-chained hydrocarbons are typically attached through ester linkages in bacteria/eukaryotes and by ether linkages in archaea. In bacteria and procaryotes, the lipids consist of diesters commonly of C16 or C18 fatty acids. The…
