Hooper Preface This is a bilingual teaching for the required course Biochemistry with spoken English and noted Chinese. The purpose of this lesson is to enhance student’s ability of reading English textbook and journal of life sciences. Introduction Foundations of Modern Biochemistry Biochemistry: An Interdisciplinary Science Uses of Biochemistry Teaching Plan Teaching Arrangement Subject Achievement Foundations of Modern Biochemistry Goals of biochemistry Biochemistry seeks to describe the structure, organization, and functions of living matter in molecular terms. Foundations of Modern Biochemistry It can be divided into three principal areas: (1) The structural chemistry of the components of living matter and the relationship of biological function to chemical structure. (2) Metabolism – the totality of chemical reactions that occur in living matter. (3) The chemistry of processes and substances that store and transmit biological information (Molecular Genetics). Note All living matters usually have the following properties : (1) movement (2) irritability(应激性 ) (3) growth (4) adaptation (5) reproduction Foundations of Modern Biochemistry Biochemistrys roots as a distinct field of study date to (起始于) the early 19th century by Friedrich W?hler. Foundations of Modern Biochemistry 1930-1950, electron microscope: provided a whole new level of insight into cellular structure. subcellular organelles could be studied, like mitochondria and chloroplasts realized that specific biochemical processes were localized in these subcellular particles. Foundations of Modern Biochemistry Nucleic acids had been isolated in 1869 by Friedrich Miescher, but their chemical structures were poorly understood, and in the early 1900s they were thought to be simple substances, fit only fo
