【biochemistry】Biochemistry is a branch of science that combines biology and chemistry to study the chemical processes within and related to living organisms. It focuses on the structure, function, and interactions of biomolecules such as proteins, nucleic acids, carbohydrates, and lipids. By understanding these molecular mechanisms, biochemists can uncover the fundamental principles of life and apply this knowledge to various fields including medicine, genetics, and biotechnology.
总结
Biochemistry explores the chemical basis of biological functions at the molecular level. It plays a crucial role in understanding how cells work, how genetic information is stored and used, and how metabolic processes support life. This field has led to significant advancements in drug development, disease diagnosis, and the treatment of genetic disorders.
