Biochemistry researchers not only apply the unique techniques of biochemistry, but also get more and more enlightenment from the techniques and ideas of genetics, molecular biology and biophysics and make comprehensive use of them. Through the in-depth study of the structure and function of biological macromolecules in biochemistry, many mysteries such as metabolism, energy conversion, genetic information transmission, photosynthesis, nerve conduction, muscle contraction, hormone action, immunity and intercellular communication have been revealed, which has made people's understanding of the nature of life leap to a new stage. In addition, biochemistry, as a bridge between biology and physics, presents important and complicated problems raised in the life world to physics, and produces frontier disciplines such as biophysics and quantum biochemistry, thus enriching the research content of physics and promoting the development of physics and biology.
