C12H16N2O

C12H16N2O is the molecular formula for several chemical compounds, including caffeine. Caffeine is a natural stimulant most commonly found in tea, coffee, and cocoa beans. It is a psychoactive drug, meaning it affects the brain and mood. Caffeine works by blocking the effects of adenosine, a neurotransmitter that promotes relaxation and sleepiness. This leads to increased alertness and reduced fatigue.

In addition to its stimulant properties, caffeine also has diuretic effects, meaning it can increase urine production. It can also stimulate the release of adrenaline, which can lead to a temporary increase in heart rate and blood pressure. Caffeine is metabolized in the liver and is excreted from the body through urine.

While caffeine is generally considered safe for most people in moderate amounts, excessive consumption can lead to side effects such as insomnia, nervousness, jitters, and an upset stomach. Individuals with certain medical conditions, such as heart problems or anxiety disorders, may be more sensitive to the effects of caffeine and should consume it with caution. Caffeine is also a component in some over-the-counter pain relievers and weight-loss supplements.
