The chemical reactions and pathways resulting in the formation of organic and inorganic nitrogenous compounds. The chemical reactions and pathways involving urea, the water soluble compound O=C-(NH2)2, produced in the liver by the ornithine cycle. It is the main nitrogen-containing excretion product in ureotelic animals. A cyclic metabolic pathway that converts waste nitrogen in the form of ammonium to urea. The chemical reactions and pathways involving small molecules, any monomeric molecule of small relative molecular mass. The chemical reactions and pathways resulting in the formation of an amide, any derivative of an oxoacid in which an acidic hydroxy group has been replaced by an amino or substituted amino group. The chemical reactions and pathways involving an amide, any derivative of an oxoacid in which an acidic hydroxy group has been replaced by an amino or substituted amino group, as carried out by individual cells.
