Deoxyguanosine monophosphate is a derivative of the common
nucleic acid GTP, or
guanosine triphosphate, in which the -OH (
hydroxyl) group on the 2' carbon on the nucleotide's
pentose has been reduced to just a hydrogen atom (hence the deoxy- part of the name). Additionally, the diphosphate of the name indicates that two of the
phosphoryl groups of GTP have been removed, most likely by
hydrolysis.
Deoxyguanosine monophosphate would be abbreviated dGMP.
