Caffeine is a derivative of adenosine and is also called Trimethylxanthine. It is composed of purines; structurally it is polar, and water soluble. They antagonize or inhibit many of the adenosine receptors, like the A1 receptor mentioned above. Caffeine affects neurons and glial cells in the brain by binding to the same location that adenosine would bind and then induce a cascade of enzymatic downstream effects. | Caffeine is a derivative of adenosine and is also called Trimethylxanthine.
