How Does Caffeine Affect Adenosine?
Adenosine is a naturally occurring organic compound that is important to the biochemistry of living organisms, including humans. In medicine, it is also sometimes given intravenously to treat heart conditions. Caffeine induces feelings of alertness and increased energy as a result of its interactions with adenosine receptors in the brain.
Chemistry
The chemical formula of adenosine is C10H13N5O4. It is a type of chemical called a purine nucleoside, a term describing its molecular structure. Purine compounds are composed of two linked ring-shaped structures of atoms called aromatic rings, which have unusually high chemical stability. A nucleoside is a compound in which a compound called a nucleobase, or simply a base, is bonded with a molecule of either ribose (C5H10O5) or deoxyribose (C5H10O4), both of which are simple sugars or monosaccharides. Adenosine consist of ribose combined with the purine adenine (C5H5N5).
Effects
It helps to regulate arousal and sleep and protect cells from damage. The amount of the substance in the body gradually increases during waking hours. Due to its inhibitory effect on the nervous system, this eventually begins to cause drowsiness and finally sleep, at which point the amount of the chemical in the body starts dropping again. Additionally, it is a component of several larger, related molecules with important functions such as intracellular messaging and providing energy for metabolism.
It also has medical uses. When injected into the bloodstream, it slows the heart rate due to its electrical effects on the atrioventricular node, which regulates heartbeat, and inhibit the release of the neurotransmitter norepinephrine.
Caffeine and Adenosine
Caffeine's effects of increasing energy and making you feel more alert are due to its interaction with adenosine(58-61-7) receptors in the brain. Both caffeine and adenosine are neurotransmitters belonging to a chemical group known as xanthine. In your brain, caffeine appears as adenosine to nerve cells and is able to bind to adenosine receptor sites. As a result, your brain does not detect it, and nerve activity does not slow down. Instead, caffeine increases brain activity, making you feel more energetic and less sensitive to your body's natural rhythms of wakefulness and sleep.
Caffeine is a common ingredient in acetaminophen-based pain relievers because it constricts blood vessels at the adenosine receptor site. It is an important factor in headaches and migraines, but its exact role is poorly understood; however, while caffeine can help relieve pain, it can also have the opposite effect. With regular consumption, your central nervous system develops a dependency on the substance that can produce painful experiences of withdrawal.
