Knowledge of chemical elements forms the foundation of quantitative analysis in biochemical experiments because all biomolecules are composed of specific elements such as carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. Understanding the atomic structure, valency, and atomic mass of these elements allows scientists to determine molecular formulas, calculate molecular weights, and predict chemical behavior. For example, calculating the molecular mass of glucose or amino acids depends on accurate knowledge of the atomic masses
