The Predominant Lipid in the Cell Membrane is A

Question

The predominant lipid in the cell membrane is a
A) triglyceride.
B) glycolipid.
C) phospholipid.
D) prostaglandin.
E) cholesterol.

Accepted Answer

Phospholipids are the predominant lipid in the cell membrane, making up approximately 50% of the membrane. They are composed of a polar head and nonpolar tails and form a bilayer structure that provides the membrane with its barrier properties. Triglycerides are primarily used for energy storage, glycolipids are important for cell-cell recognition, prostaglandins are signaling molecules, and cholesterol helps regulate membrane fluidity.
