Which property is NOT associated with lipids?

Lipids are characterized by their hydrophobic nature, meaning they do not mix well with water. This hydrophobic property explains why lipids are associated with low solubility in water, as their molecular structures are largely composed of long hydrocarbon chains or ring structures that repel water molecules.

In contrast, lipids do exhibit high solubility in non-polar solvents due to their non-polar characteristics. The amphipathic nature of some lipids, such as phospholipids, allows them to have both hydrophobic and hydrophilic regions, enabling them to form biological membranes. However, the defining feature in this context is that lipids are generally not soluble in water. Thus, the property of high solubility in water is not associated with lipids, making it the correct answer.
