These molecules include: Proteins: Proteins are complex macromolecules made up of amino acids. They play crucial roles in various biological processes, serving as enzymes, structural components, and signaling molecules.Nucleic Acids: Nucleic acids, such as DNA and RNA, store and transmit genetic information. They are responsible for heredity and control of cellular activities.Lipids: Lipids are various molecules that include fats, phospholipids, and steroids. They serve as a store of energy, cell membrane components, and signaling molecules.Carbohydrates: Carbohydrates are sugars and starches that provide energy and structural support. They are essential for cellular respiration and serve as cellular markers. Enzymes: The Catalysts of Life Enzymes are proteins that act as catalysts, accelerating chemical reactions in biological systems. They are fundamental to the functioning of living organisms. Enzymes reduce the activation energy required for reactions, allowing them to occur at biologically relevant temperatures and times. Enzymes play a fundamental role in metabolic pathways, DNA replication, protein synthesis and many other cellular processes. Their specificity and efficiency are critical to maintaining the delicate balance of life-sustaining reactions within cells. Energy and metabolism The study of biochemistry provides insights into the energy transformations that occur within living organisms. Cellular metabolism, which includes all chemical reactions in cells, involves the conversion of nutrients into energy and the building of cellular structures. Key metabolic processes include: Glycolysis: the breakdown of glucose to produce energy in the form of adenosine triphosphate (ATP). Krebs Cycle: A series of reactions that generate high-energy electrons for the electron transport chain. Photosynthesis: The process by which plants and some bacteria convert light energy into chemical energy in the form of glucose. Genetic Information and DNA Understanding biochemistry is closely linked to the study of genetics and DNA. DNA, or deoxyribonucleic acid, carries the genetic instructions for the development, functioning, growth, and reproduction of all known living organisms. The double helix structure of DNA, explained by James Watson and Francis Crick, is a masterpiece of biochemistry. The complementary base pairing of adenine with thymine and cytosine with guanine ensures the faithful replication and transmission of genetic information. Importance in Medicine and BiotechnologyBiochemistry is not limited to the laboratory; has profound implications for medicine and biotechnology. Medical biochemistry plays a vital role in the diagnosis and treatment of diseases. It involves analyzing biomarkers, enzymes and metabolic pathways to identify health problems and develop therapies.
