Biochemistry is the branch of science that explores the chemical processes and substances that occur within living organisms. It combines principles from both biology and chemistry to study biomolecules like proteins, nucleic acids, carbohydrates, and lipids. Biochemists investigate how these molecules interact, how they contribute to the structure and function of cells, and how metabolic pathways operate. This field plays a crucial role in areas such as medicine, genetics, and biotechnology.
