Hydrophilicity refers to the property of a substance that allows it to interact well with water. Materials that are hydrophilic tend to attract water molecules, often resulting in the formation of hydrogen bonds. This characteristic is important in various fields, including biology, chemistry, and materials science, as it influences how substances behave in aqueous environments.
Common examples of hydrophilic substances include sugars, salts, and alcohols. These materials can dissolve easily in water, making them essential in processes like nutrient transport in living organisms and the formulation of pharmaceuticals. Understanding hydrophilicity helps scientists design better products and improve chemical reactions.
