Pure caffeine is a white, tasteless substance that makes up as much as 5% of. the weight of tea leaves. By structure, caffeine is closely related to the purine bases, guanine and adenine, found in deoxyribonucleic acids (DNA).
It belongs to the group of compounds. known as methylxanthines which include. theobromine (cocoa) and theophylline (tea). Because of its excellent solubility and slow rate. of degradation, caffeine can persist in aquatic. environments (Seiler et al., 2005) and has the. potential to biomagnify through the food chain. Thus, even a small amount of dissolved caffeine. in aquatic environment can concentrate over. time.
