    structure is relatively similar to the nucleic acid purine in that they use nitrogen and is bicyclic but lacks an alkene‚ amine and an amide. Caffeine has a solubility of 67.0 g/100 mL in boiling water but tannins also boil in hot water to form catechin. Catechin cannot react with water but it can with calcium carbonate. The calcium carbonate was added into the reflux beforehand so the catechins can quickly change to form glucose and salts of gallic
