The chemical complexity of coffee is emerging, especially due to observed physiological effects which cannot be related only to the presence of caffeine. Moreover, coffee contains an exceptionally substantial amount of antioxidants such as chlorogenic acids, hydroxycinnamic acids, caffeine and Maillard reaction products, such as melanoidins. [3]
The world's primary source of caffeine is the coffee "bean" (the seed of the coffee plant), from which coffee is brewed. Caffeine content in coffee varies widely depending on the type of coffee bean and the method of preparation used; [ 240 ] even beans within a given bush can show variations in concentration.
One psychoactive chemical in coffee is caffeine, an adenosine receptor antagonist that is known for its stimulant effects. [168] Coffee also contains the monoamine oxidase inhibitors β-carboline and harmane, which may contribute to its psychoactivity. [169] In a healthy liver, caffeine is mostly broken down by hepatic enzymes.
A coffee bean is a seed from the Coffea plant and the source for coffee. ... Further, such molecules have antioxidative activity due to their chemical structure. [36]
The compound is obtained from cinchona bark, coffee beans, and the bark of Eucalyptus globulus. [2] It is a constituent of the tara tannins. Urtica dioica, the European stinging nettle, is another common source. [3] It is made synthetically by hydrolysis of chlorogenic acid. Quinic acid is also implicated in the perceived acidity of coffee.
