生物化学涉及生物中的化学和物理元素以及细胞生成和发展的生物学功能的科学。许多生物化学有关生物化学作用和基础实验的原始理论经历了革命性的现代化，现在范围更广。除健康科学外，生物化学已成为私营行业的一门强大科学，其范围从污染物分解分析到新药测试。除了许多其他技能，生物化学家还可以分离，分析和合成蛋白质，酶，DNA和其他分子。他们还研究了药物，激素和食物等物质对生物过程的影响。
Biochemistry involves the science of chemical and physical elements in living things and the biological functions of cell generation and progression. Many of biochemistry's original theories on biochemical action and basic experimentation have experienced a revolutionary modernization and now are much more broad. In addition to health sciences, biochemistry has become a powerful science in private industry, ranging from the analysis of pollutant decomposition to new drug testing. Among many other skills, biochemists isolate, analyze and synthesize proteins, enzymes, DNA and other molecules. They also research the effects of substances such as drugs, hormones and food on biological processes.
