Paraxanthine, also known as 1,7-dimethylxanthine, is an isomer of theophylline and theobromine, two well-known stimulants found in coffee, tea, and chocolate mainly in the form of caffeine. It is a member of the xanthine family of alkaloids, which includes theophylline, theobromine and caffeine.
The elimination half life of theobromine is between 6 and 8 hours. [1] [2] Unlike caffeine, which is highly water-soluble, theobromine is only slightly water-soluble and is more fat soluble, and thus peaks more slowly in the blood. While caffeine peaks after only 30 minutes, theobromine requires 2–3 hours to peak. [29]
Other alkaloids possess psychotropic (e.g. psilocin) and stimulant activities (e.g. cocaine, caffeine, nicotine, theobromine), [11] and have been used in entheogenic rituals or as recreational drugs. Alkaloids can be toxic too (e.g. atropine , tubocurarine ). [ 12 ]
Caffeine is the world's most widely consumed psychoactive drug. [20] [21] Unlike most other psychoactive substances, caffeine remains largely unregulated and legal in nearly all parts of the world. Caffeine is also an outlier as its use is seen as socially acceptable in most cultures with it even being encouraged.

Several stimulants are derived from xanthine, including caffeine, theophylline, and theobromine. [3] [4] Xanthine is a product on the pathway of purine degradation. [2] It is created from guanine by guanine deaminase. It is created from hypoxanthine by xanthine oxidoreductase. It is also created from xanthosine by purine nucleoside phosphorylase.
Caffeine content . About 76 mg per cup. Possible health benefits. Reduces inflammation, Boosts immune system and protects cells, Lowers stress and enhances mental clarity. Potential side effects.
Interactions between chemical compounds also is a frequent area of taxonomy, as are the major organic chemistry categories (protein, carbohydrate, lipid, etc.) that are relevant to the field. In the field of aroma and flavor alone, Flament gives a list of 300 contributing chemicals in green beans, and over 850 after roasting.
