As far the catalytic activity of saccharin and its derivatives is concerned it is found to be more effective with good yield than the standard archetype catalyst. But Roosevelt himself was a consumer of saccharin, and, in a heated exchange, Roosevelt angrily answered Wiley by stating, "Anybody who says saccharin is injurious to health is an idiot." Alkanes, alkenes, and alkynes are all classified as hydrocarbons, because they are composed solely of carbon and hydrogen atoms. Functional groups and organic nomenclature.

[38], Saccharin can be produced in various ways. 40, pp. For example the structure of capsaicin, found in chili peppers, incorporates several functional groups, labeled in the figure below and explained throughout this section. The results indicate that the presence of a benzene ring in saccharin, benzene sulfonic acid and benzothiazole cause these molecules to move from the electrolyte to the electrode surface and, by blocking the electrode surface, enhance the grain size and produce nickel coatings with an average grain size below 50 nm. Consistently, the functional enrichment analysis of the gut microbes also displayed a huge distinction in bacterial functional repertoire between the saccharin and control group. Water (H2O) is not carbon-based, therefore it is considered an inorganic compound.
