MCQ (Single Correct)

The main phospholipids in most animal cell membranes are the

Phosphoglycerides. Correct Phosphosphingolipids Ceramide phosphoryllipids Sphingomyelins.

Lipid Composition of Animal Plasma Membranes:
Phosphoglycerides (Glycerophospholipids) constitute the overwhelming majority ($\gt 50 - 70\%$) of the total phospholipid content of animal cell membranes.
Consist of a glycerol backbone esterified to two fatty acid chains and a phosphorylated polar alcohol headgroup:

$$\text{Phosphatidylcholine (PC), Phosphatidylethanolamine (PE), Phosphatidylserine (PS), Phosphatidylinositol (PI)}$$

Sphingolipids (sphingomyelin) constitute a minor fraction concentrated in lipid rafts.
nalysis:
(Phosphoglycerides): Correct.

Correct option: (1) Phosphoglycerides.
