Inosine occurrence

The new additives allowed to be used in Australia (627—disodium guanylate, 631—disodium inosinate, and 635—disodium 5 -ribonucleotides) are associated with occurrence of skin rashes in hypersensitive persons (Table 14.4.2).

Inosine-5 -phosphate can be converted to the nucleotides of adenine and guanine, well-known components of nucleic acids. Here, however, we are concerned with other possible means of utilizing this substance. For when one talks of purine alkaloids, one thinks primarily of caffeine, theophylline, and theobromine (Fig. 131). These methylated purine alkaloids are widely distributed, especially caffeine. Its occurrence in coffee (among others, Coffea arabica), tea Camellia sinensis), and cocoa Theobroma cacao) is well-known.
