hidrofiilisyyttä
Hydrophilicity refers to the property of a molecule or substance to be attracted to, absorb, or dissolve in water. The term is derived from Greek words, where "hydro" means water and "philos" means loving. Substances that exhibit hydrophilicity are considered polar and tend to form hydrogen bonds with water molecules. This attraction arises from the presence of polar functional groups, such as hydroxyl (-OH), carboxyl (-COOH), amino (-NH2), or ether (C-O-C) groups, within the molecule's structure. These groups can readily interact with the partial positive charges on hydrogen atoms or the partial negative charges on oxygen atoms of water molecules.
Conversely, substances that are repelled by water are called hydrophobic. Hydrophilic substances are soluble in water,
