Understanding Phospholipids and Their Unique Structure

In organic chemistry, biomolecules are essential for life and are categorized into different classes such as proteins, nucleic acids, carbohydrates, and lipids. A common structure among biomolecules is the presence of functional groups that facilitate biochemical reactions. Consider a molecule identified as a phospholipid, which plays a critical role in cell membrane structure.

This phospholipid contains a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails, making it amphipathic. These properties are significant for the formation of lipid bilayers in cellular membranes.

Given this context, identify which statement correctly describes a unique aspect of phospholipids compared to other types of biomolecules.
