生物化学在最近的五六十年有着惊人的发展。它原是由于医学和农学上的要求而产生的科目,但是目前它已经由婴儿迅速地长到成年。它已经由医农的附庸,发展到范围日益扩展的独立科目;它也已经从致力于组织化学的静科学,转入注重代谢和功能的动科学。生物化学的领域,至为广阔,范围甚难规定,和各隣近科目接壤的地方又特别多,缺乏明确的界限。例如生理学、临床化学、有机化学、药理学 Biochemistry has seen phenomenal growth in the last 50-60 years. Originally due to medical and agronomic requirements, it has now grown rapidly from infant to adulthood. It has evolved from a vassal of medical practitioners to a growing number of independent subjects; it has also moved from static science, which is devoted to organizing chemistry, to dynamic science, which focuses on metabolism and function. The field of biochemistry is vast in scope and very difficult to stipulate. There are so many places that are bordered by the neighboring subjects that there is no definite boundary. For example, physiology, clinical chemistry, organic chemistry, pharmacology
