Biochemistry is an interdisciplinary scientific field that investigates the chemical processes that occur within living organisms. It examines the structure, function, and interactions of the macromolecules essential to life, including proteins, carbohydrates, lipids, and nucleic acids. The discipline explores metabolic pathways, enzyme kinetics, and the molecular basis of heredity and metabolism. By analyzing these chemical reactions, biochemistry provides fundamental insights into biological processes, ranging from energy storage and transformation to the mechanisms of cellular communication and the structural integrity of biological systems.
