Knowra Biochemistry Biochemistry Biochemistry studies the chemical substances and reactions of living organisms, explaining how molecules build cells, transfer energy, and regulate life.
Proteins : Proteins are chains of amino acids that fold into structures with roles in catalysis, transport, signaling, and cellular support. Their structures and activities are among biochemistry’s main objects of study.
Metabolism : Metabolism is the complete set of chemical reactions that sustain an organism, including synthesis and breakdown of molecules. It organizes biochemical reactions into linked routes for acquiring and using matter and energy.
Vitalism : Vitalism is the view that living systems depend on a special force distinct from physical and chemical processes. Biochemistry emerged in opposition to explanations that placed life beyond chemistry.
Clinical biochemistry : Clinical biochemistry analyzes substances in blood and other body fluids to support diagnosis and monitoring. It applies biochemical measurements to health assessment and disease management.
DNA : DNA is a nucleic acid that stores hereditary information in most organisms. Its structure and replication gave heredity a chemical mechanism.
Nucleic acids : Nucleic acids are polymers, including DNA and RNA, that store, transmit, or help use genetic information. Their chemistry underlies the storage and expression of biological information.
Glycolysis : Glycolysis is a sequence of reactions that converts glucose into pyruvate while producing ATP and NADH. It is a well-studied pathway for extracting energy from glucose.
Friedrich Wöhler : Friedrich Wöhler was a German chemist who synthesized urea from inorganic compounds in 1828. His synthesis challenged the idea that organic substances required a living source.
Molecular biology : Molecular biology studies biological processes through the interactions of DNA, RNA, proteins, and other molecules. It shares biochemistry’s focus on molecular mechanisms while emphasizing genetic information.
Central dogma of molecular biology : The central dogma describes the usual flow of sequence information from DNA to RNA to protein. It summarizes how biochemical processes connect genes to cellular function.
