hüdrofiilne
hüdrofiilne is an adjective used to describe a substance or molecule that has an affinity for water. These substances are typically polar or charged, allowing them to readily interact with and dissolve in water, which is also a polar solvent. The term originates from the Greek words "hydor" meaning water and "philos" meaning loving. In contrast, substances that repel water are described as hüdrofoobne, meaning water-fearing. Many biological molecules, such as carbohydrates and proteins, contain hüdrofiilne regions that enable them to function within the aqueous environment of living cells. The solubility of a compound is directly related to its hüdrofiilne or hüdrofoobne character. For example, salts, which are ionic compounds, are highly hüdrofiilne and dissolve easily in water. Conversely, oils and fats, which are nonpolar, are hüdrofoobne and do not mix with water. Understanding the hüdrofiilne nature of molecules is crucial in various fields, including chemistry, biology, and medicine, as it influences processes like chemical reactions, membrane transport, and drug delivery.
