 It differs from the energy-transferring molecule adenosine triphosphate (ATP) by a single hydroxyl group (the -OH group on the 2' carbon of the pentose sugar is replaced by -H in dATP), resulting in a deoxyribose instead of a ribose.Two phosphate groups can be hydrolyzed to yield deoxyadenosine monophosphate, which can then be used to synthesize DNA.Findings have also suggested that dATP can act as an energy-transferring molecule to maintain cell viability.
