Biochemistry is a scientific discipline that explores the chemical processes and molecules that occur within living organisms. It combines principles of biology and chemistry to study the structure, function, and interactions of biological macromolecules such as proteins, nucleic acids, carbohydrates, and lipids. Biochemists investigate how these molecules contribute to the overall functioning of cells, tissues, and organisms, including processes such as metabolism, gene expression, signal transduction, and cell communication. They utilize various techniques and tools, including spectrophotometry, chromatography, and molecular biology methods, to analyze and manipulate biomolecules. Biochemistry plays a crucial role in understanding the molecular basis of life, developing new drugs and therapies, investigating diseases, and advancing fields such as genetics, biotechnology, and pharmacology. It provides insights into the intricate biochemical pathways and mechanisms that underlie biological processes, contributing to our understanding of life at a molecular level.
