The three main components of the lipid bilayer portion of a plasma membrane are

The correct answer is - phospholipids, cholesterol, and glycolipids.

Explanation:

The three main and major lipid molecules present in the plasma membrane are phospholipids, glycolipids, and cholesterol. The most abundant lipid form found in the lipid bilayer is the phospholipid. In phospholipid a poplar head and two hydrophobic tails are present.

Glycolipids are found only on the outer leaflet of the plasma membrane. It constitutes 5-10% of lipid bilayer. Cholesterol and glycolipid together can make 40 percent of lipid bilayer. Plant cell plasma membrane lacks cholesterol but they have other sterols like stigmasterols.
