生物化学是一门非常广泛的科学，它研究生命的分子和化学。生物化学专注于蛋白质，核酸，糖和脂质等分子的结构，性质和相互作用。生物化学的目的是了解这些分子如何参与支持生命细胞各种功能的过程。因此，这些研究对于理解疾病和寻找治疗方法，改善农业以及粮食和生物燃料的生产以及生物技术的创新至关重要。
Biochemistry is a very broad science that studies the molecules and chemistry of life. Biochemistry focuses on the structure, properties, and interactions of molecules such as proteins, nucleic acids, sugars and lipids. Biochemistry's aim is to understand how these molecules participate in the processes that support the various functions of the living cell. These studies are therefore essential for understanding disease and finding cures, for improving agriculture and the production of food and biofuels, and to produce innovation in biotechnology.<br><br>Whereas other biological science majors may focus on cellular, organismal, or population-level biology, biochemistry focuses on processes that occur at the molecular to cellular levels. Therefore, this major has a greater focus on basic and quantitative sciences, such as math and, particularly, on chemistry.
