− | '''Phosphorus has many key functions, principally as a component of compounds essential to normal metabolism'''. These include: phospholipids and phosphoproteins that are important in membrane formation; the nucleic acids [[DNA]] and RNA; other nucleotides such as ATP that are vital components of energy metabolism; enzyme cofactors. Phosphorus also has a role in regulating acid-base balance. | + | '''Phosphorus has many key functions, principally as a component of compounds essential to normal metabolism'''.
