Fig.1: Guanosine diphosphate
Explanation of Solution
Explanation:
The given structure in the diagram is of the nucleoside diphosphate called guanosine diphosphate, as identified by its components (Fig.1). The nucleobase in the given structure is the purine derivative guanine, which has the formula C5H5N5O1. It is a planar and bicyclic molecule. It contains a pyrimidine-imidazole fused ring structure with conjugated double bonds. Ribose sugar is an organic single-ring 5-carbon compound. It consists of five carbon atoms, five oxygen atoms, and ten hydrogen atoms that are bonded together. The guanine and ribose sugar together form the nucleoside guanosine, which is attached to the diphosphate moiety. Diphosphate is an ester that contains two phosphate groups.
