Funktioryhmä
Funktioryhmä is a Finnish term that translates to "function group" or "functional group" in English, commonly used in chemistry and mathematics. In chemistry, a functional group is a specific group of atoms or bonds within a molecule that is responsible for the characteristic chemical reactions of that molecule. For example, a hydroxyl group (-OH) is a functional group found in alcohols, and a carbonyl group (C=O) is characteristic of aldehydes and ketones. The presence and arrangement of functional groups determine a molecule's properties, such as its polarity, reactivity, and physical state. Understanding functional groups is fundamental to organic chemistry, allowing chemists to predict how molecules will behave and to design new compounds.
In mathematics, particularly in abstract algebra, a funktioryhmä can refer to a group whose elements are functions.
