- Low water solubility
- Nonpolar nature
- Tendency to aggregate in non-aqueous environments
Examples of Hydrophobic Substances
- Fats and oils
- Wax
- Grease
Section 2: Hydrophilicity: Embracing Water
Definition and Characteristics
In contrast to hydrophobicity, hydrophilicity describes the affinity or attraction towards water molecules. Hydrophilic substances readily dissolve or disperse in water.
Key Characteristics:
- High water solubility
- Polar nature
- Ability to form hydrogen bonds with water molecules
Examples of Hydrophilic Substances
- Sugar
- Salt
- Cellulose

FAQ Section: Addressing Common Questions
1. Can a substance be both hydrophobic and hydrophilic?
No, a substance cannot possess both properties simultaneously. The molecular structure dictates whether a substance will exhibit hydrophobic or hydrophilic characteristics.
2. How do hydrophobic and hydrophilic properties impact biological systems?
In biological systems, these properties influence the behavior of cell membranes, the solubility of drugs, and the interactions between biomolecules.
3. Are there any health implications associated with hydrophobic or hydrophilic substances?
While hydrophobic substances may accumulate in certain tissues, hydrophilic substances are often easily eliminated from the body. Health implications depend on the specific nature of the substances involved.
