Gammafosfaattiryhmä

Gammafosfaattiryhmä, also known as gamma-phosphoryl group, is a functional group in organic chemistry. It consists of a phosphate group (PO4) attached to a carbon atom via a single bond, with the phosphate group positioned at the gamma (γ) position relative to the carbon atom. This group is commonly found in various biological molecules, including nucleotides, phospholipids, and certain proteins.

The gammafosfaattiryhmä plays a crucial role in biological systems. In nucleotides, it is a key component of the phosphate backbone of DNA and RNA, where it forms phosphodiester bonds between nucleotides. In phospholipids, the gammafosfaattiryhmä is part of the glycerol backbone, which anchors the phospholipid to the cell membrane. In proteins, it can be found in post-translational modifications, such as phosphorylation, where it is added to serine, threonine, or tyrosine residues.

The gammafosfaattiryhmä is also important in synthetic chemistry. It can be used to introduce phosphate groups into organic molecules, which can have various applications, such as in the synthesis of pharmaceuticals, agrochemicals, and materials science. The group can be introduced through various chemical reactions, such as phosphorylation, where a phosphate group is transferred from a phosphate donor to an acceptor molecule.
