Note: IUPAC defines a molecule as "An electrically neutral entity consisting of more than one atom".However, traditionally the definition would include the single atoms of the noble gases as molecules.

Introduction. All tissues have some capability for synthesis of the non-essential amino acids, amino acid remodeling, and conversion of non-amino acid carbon skeletons into amino acids and other derivatives that contain nitrogen.However, the liver is the major site of nitrogen metabolism in the body. In times of dietary surplus, the potentially toxic nitrogen of amino acids is eliminated via.
