Biochemistry is the study of the chemical processes and substances that occur within living organisms. It combines the principles and theories of both biology and chemistry to understand the molecular mechanisms that drive life. Biochemists investigate the structure and function of biological molecules such as proteins, nucleic acids, carbohydrates, and lipids. They study how these molecules interact and contribute to the normal functioning of cells and organisms. Biochemistry plays a crucial role in various fields, including medicine, pharmacy, agriculture, and environmental science. It helps in the development of new drugs, understanding diseases at a molecular level, genetic engineering, and the production of biofuels. With its interdisciplinary nature, biochemistry continues to advance our understanding of life and pave the way for innovative technological and medical advancements.
