Natural products chemistry is the chemistry of metabolite products of plants, animals, insects, marine organisms and microorganisms. The metabolic products include alkaloids, flavonoids, terpenoids, glycosides, amino acids, proteins, carbohydrates etc. The applications of natural products range from medicines, to sweeteners and pigments. The development of new technology, including information technology, promotes the mutual penetration of different scientific fields. Natural products chemistry has been involved in the investigation of many biological phenomena, such as drug mechanisms to gametophytes and receptors, drug metabolism in the human body, and protein and enzyme chemistry. Natural products chemistry is also associated with the chemistry of endogenous products and biochemistry. The book titled Comprehensive Natural Products Chemistry and edited by D.H. R. Barton et al., mainly expounded on the chemistry of enzyme, protein, DNA, RNA, polysaccharide and other life related compounds.
