Biochemistry is the scientific study of the chemical and physical processes that occur within living organisms. It focuses on the chemical reactions that take place in cells and the molecules that are involved in these reactions, including proteins, carbohydrates, lipids, and nucleic acids. Biochemistry seeks to understand the molecular mechanisms of biological processes, such as metabolism, DNA replication, and protein synthesis, and how they are regulated.
Biochemists use a variety of techniques, including spectroscopy, chromatography, and electrophoresis, to study the properties and interactions of biological molecules. They also use techniques from other fields such as genetics, microbiology, and cell biology to understand how biological processes work at the molecular level. Some areas of research in biochemistry include enzymology, metabolism, structural biology, and molecular genetics.
Biochemistry has many practical applications in fields such as medicine, agriculture, and biotechnology. For example, biochemists may work to develop new drugs, study the effects of pollutants on the environment, or engineer bacteria to produce useful chemicals.
