What are phospholipid components?

What are phospholipid components?

• A. Cholesterol nucleus
• B. Glycerol backbone and three fatty acids
• C. Glucose and two fatty acids
• D. Glycerol backbone, 1 phosphate group and 2 fatty acid tails

Answer: (D)

Phospholipids are built around a glycerol backbone with two fatty acid tails and a phosphate-containing head group. This arrangement creates a hydrophilic (water-loving) head and hydrophobic (water-fearing) tails, enabling them to form membranes with a bilayer structure. The correct description is glycerol backbone, one phosphate group, and two fatty acid tails. The other options describe structures that aren’t phospholipids: a triglyceride has three fatty acids, a cholesterol-centered idea isn’t a phospholipid, and glucose attached to fatty acids isn’t the phospholipid layout.
