Verified
Which of the following statements about phospholipids is false ?
A) They are amphipathic molecules.
B) They contain three fatty acids chains.
C) They contain a polar organic group attached to a phosphate group.
D) They have cylindrical shapes that allow them to associate with water most easily as a bilayer structure.
E) They have two distinct regions, one strongly hydrophobic and the other strongly hydrophilic.
Amphipathic
A molecule having both hydrophilic (water-loving) and hydrophobic (water-repelling) parts.
Phospholipids
A class of lipids that are a major component of all cell membranes, consisting of two fatty acids, a phosphate group, and a glycerol molecule.
Fatty Acids
Long chains of hydrocarbon molecules with a carboxylic acid group, which are components of lipids and play roles in energy storage and cellular structure.

Final Answer :
B
Explanation :
Phospholipids typically contain two fatty acid chains, not three. The presence of three fatty acid chains is characteristic of triglycerides, not phospholipids.
