Quizplus · Accepted Answer

Adenosine and its derivatives belong to the category of purines, which are nitrogen-containing compounds that serve many functions in the body, including as energy carriers (e.g. ATP), signaling molecules (e.g. adenosine), and DNA/RNA building blocks. Neuropeptides, acetylcholine, and monoamines are other categories of chemicals that play important roles in the nervous system, but they do not include adenosine or its derivatives.
