Fosfaatrühma

Fosfaatrühma, also known as phosphate group, is a functional group in organic chemistry that consists of a phosphorus atom bonded to four oxygen atoms. The general formula for a fosfaatrühma is PO4^3-. This group is a polyatomic ion, meaning it carries a charge of -3 when it is not bonded to other atoms. Fosfaatrühmas are commonly found in biological molecules such as DNA, RNA, and ATP, where they play crucial roles in energy transfer and genetic information storage. In organic synthesis, fosfaatrühmas are often used as leaving groups in substitution reactions. They can also be used to introduce phosphorus-containing functional groups into organic molecules. Fosfaatrühmas can exist in different forms, including mono-, di-, and triesters, depending on the number of oxygen atoms bonded to the phosphorus atom. The fosfaatrühma is a versatile functional group with a wide range of applications in chemistry and biology.
