Biochemists study the structure, composition, chemical processes and chemical reactions in living organisms. They analyze the chemical reactions in the cells and tissues of living things, study the expression of genes, and research on the effects of food, medicine and other substances on living tissues. Biochemistry is an interdisciplinary field and encompasses elements of molecular biology, molecular genetics, microbiology, and organic and inorganic chemistry. Pure research in biochemistry is conducted to further human knowledge of the subject while applied research is conducted to solve practical problems. The work of biochemists is applicable to a variety of fields like medicine, food science, agriculture and industry. In human and veterinary medicine, biochemists analyze drug function and mechanism, and help in the development of new drugs. Biochemists engaged in agriculture and food science determine the chemical composition of foods to explore different sources of nutritious food, and study the effects of herbicides and other chemicals on crop plants. They use advanced tools and techniques like radioactive isotopes, spectrophotometers, centrifuges, electron microscopes and specialized software to perform experiments.
