Caffeine (Chemist's molecular name: 1,3,7 Trimethylxanthine) biologist's functional name: (Selective Adenosine Reuptake antagonist/blocker [SSRI, SAAA]) is a relatively large molecule of between 100 and 200 members of elemental Oxygen, Nitrogen Hydrogen and others, that is mistaken by your brain for the naturally created regulatory neurotransmitter: Adenosine that is designed to be a "key in lock" messenger molecule, made by a small organ on top of your kidneys. The Adenosine receptors lining axon body and synaptic cleft of neurons in your brain, and stomach/intestinal lining, specifically the (A1, A2a, A2b, and A3) use the messenger to be a throttle on Your body's energy update currency and energy output spending plan. Adenosine triphosphate (ATP) and enzymes in your blood break down naturally occurring Adenosine and its imposter Caffine by ripping its wings off. These neurotransmitters are how your body creates the clock that optimally tunes neural networks for performance time and retraining time throughout your body (brain and gut) for power strokes on: "We need a perfect response now" and "We want to rebuild the network of network strokes during sleep" (day and night cycles, and emergency fleeing-predator mode vs hunger mode vs you just ate mode).
