Guanosine monophosphate

Guanosine Monophosphate

Guanosine monophosphate (GMP), pronounced as /ɡwɑːˈnoʊsaɪn ˌmɒnɵˈfɒsfeɪt/, is a nucleotide that is used as a subunit in RNA (ribonucleic acid). It is an ester of phosphoric acid with the nucleoside guanosine. GMP consists of the pyrimidine base guanine linked to the 1' carbon of the ribose sugar, and to the phosphate group at the 5' position.

Etymology

The term "Guanosine monophosphate" is derived from the term "guanine", which is one of the five main nucleobases found in the nucleic acids DNA and RNA. The "-osine" suffix indicates that it is a nucleoside, and the "monophosphate" refers to the single phosphate group that is connected to the guanosine.
