Biologically active molecules: Nucleic acids including DNA and RNA

Author(s): Dr. Ranjna Sajid

Biochemistry is the study of chemical processes within living organisms. These processes are driven by a vast array of molecules that play crucial roles in maintaining the structural and functional integrity of cells and tissues. Among these molecules are biologically active compounds, which are organic molecules that have important physiological effects on the body. Biologically active molecules include a broad range of compounds, such as proteins, enzymes, nucleic acids, lipi ds, carbohydrates, and vitamins, among others. Proteins are the most abundant biologically active molecules in cells, and they perform a wide range of functions, including catalyzing chemical reactions, transporting molecules across membranes, and providing structural support. Enzymes are a type of protein that acts as catalysts, speeding up chemical reactions in cells. They are e
