Chocolate (cocoa) contains mostly theobromine and also caffeine and theophylline in low concentrations. Experts are not sure exactly how methylxanthines work but research has shown they inhibit the enzyme phosphodiesterase, antagonize adenosine receptors, and at lower dosages, their effects on histone deacetylase activity are believed to contribute to their immunomodulatory effects. Due to molecular vibration and rotation, a molecule is able to absorb light at a particular wavelength characteristic of its structure. A number of preparations containing e.g. Allopurinol is metabolized to the corresponding xanthine analogue, oxipurinol (alloxanthine), which also is an inhibitor of xanthine oxidase.
