Consider the molecule. A chemical structure shows a molecule consisting of two five carbon sugars, two phosphates, and two nitrogenous bases. Both sugars are five membered rings with free hydroxyl groups at carbon 2 and carbon 3. The two phosphate groups join carbon 5 of the first sugar to carbon 5 of the second sugar. Each phosphate group has a minus 1 charge. Each nitrogenous base is attached to carbon 1 of a sugar. The first nitrogenous base has two fused heterocyclic rings. Carbon 6 of the first base has an amino group substituent. Nitrogen 9 of the first base attaches to the sugar. The second nitrogenous base is a single heterocyclic ring with an amide group. Neither of the nitrogenous bases has a charge. Identify the molecule. FMNH2 FMNH NAD FMN NADH
