Question

Which of the following statements is not true about phospholipids?
Options
A They are similar to triacylglycerols except that the middle OH group of glycerol reacts with a phosphate rather than with a fatty acid.
Correct Answer
B They constitute a major component of cell membranes.
C Phosphatidic acid is a phospholipid.
D The C-2 carbon of glycerol in phosphoacylglycerols has the R configuration.
Correct Answer

Option A is the correct answer.

Detailed Explanation

In phospholipids, the glycerol is esterified with two fatty acids (at C1 and C2) and a phosphate at C3 (not the middle OH group, which is C2). The middle OH (C2) is esterified with a fatty acid, not phosphate.

Hint

Which position of glycerol is esterified with phosphate in phospholipids?
