Multiple Choice

Which one of the following statements is incorrect about triacylglycerols and phospholipids?

Triacylglycerols contain glycerol while phospholipids do not.

Phospholipids have a phosphate group attached at C3.

Phospholipids and triacylglycerols contain 2 and 3 fatty acids, respectively.

Due to polar head groups, phospholipids have a higher water solubility than triacylglycerols.

Verified step by step guidance

Understand the structure of triacylglycerols: They are composed of a glycerol backbone bonded to three fatty acid chains. This means they inherently contain glycerol.

Understand the structure of phospholipids: They also have a glycerol backbone, but are bonded to two fatty acid chains and a phosphate group at the third position (C3).

Compare the number of fatty acids: Triacylglycerols have three fatty acids, while phospholipids have two fatty acids and a phosphate group.

Consider the solubility: Phospholipids have a polar phosphate head, which increases their solubility in water compared to the nonpolar triacylglycerols.

Identify the incorrect statement: Since both triacylglycerols and phospholipids contain glycerol, the statement 'Triacylglycerols contain glycerol while phospholipids do not' is incorrect.
