Glycerophospholipids derive from phosphatidic acids, compounds formed by a molecule of glycerol with two of its hydroxyl groups esterified by FAs, and the third hydroxyl esterified by phosphoric acid. C2 of the glycerol moiety is asymmetric, producing stereoisomers.

What are phosphoglycerides composed?

Phospholipids are similar to the triglycerides with a couple of exceptions. Phospholglycerides are esters of only two fatty acids, phosphoric acid and a trifunctional alcohol – glycerol (IUPAC name is 1,2,3-propantriol).

Why is it that phosphoglycerides are found in cell membrane?

Membranes are therefore selectively permeable structures; a property that helps to prevent leakage and protect the cell from the passive entry of many toxins. Phosphoglycerides have a hydrophilic polar head and a hydrophobic fatty acid tail.
