Identify the structure of ribose-5-triphosphate.

Step-by-step solution

Ribose is a five-carbon sugar that forms a five-membered furanose ring. In its structure, it has hydroxyl ( - OH ) groups at the C1, C2, and C3 positions. The name "ribose-5-triphosphate" indicates that a triphosphate group (a chain of three phosphate groups) is attached to the C5 position of the ribose sugar. Analyzing the given options: Option (A) shows a ribose sugar (with - OH groups at C1, C2, and C3) attached to a chain of three phosphate groups at the C5 position. This correctly represents ribose-5-triphosph
