The study of chemical reactions that occur in living organisms is called biochemistry. This scientific discipline combines principles from both biology and chemistry to explore the molecular mechanisms underlying physiological processes. Biochemistry focuses on understanding how biomolecules such as proteins, nucleic acids, lipids, and carbohydrates interact within cells, influencing metabolism, growth, and cellular communication. Research in this field contributes significantly to advancements in healthcare, genetics, and biotechnology, elucidating the chemical basis of life and diseases.
