Metabolites and Macromolecules The major precursors for the formation of biomolecules are water,carbon dioxide,and three inorganic nitrogen compounds-ammonium (NH4+), nitrate (NO3),and dinitrogen (N2).Metabolic processes assimilate and transform these inorganic precursors through ever more complex levels of biomolecular order
