Human molecule
Iron is the 12th most abundant element in the human molecule, comprising 0.012 percent of its mass. The major function of iron is to combine with protein and copper in making hemoglobin. Iron builds up the quality of the blood and increases resistance to stress, the immune system, energy production, growth in children, and resistance to disease.

Human molecular formula
The position of the element calcium in the average human molecular formula is as follows:

Quotes
The following are related quotes:

“Is it not for want of an attractive virtue [chemical affinity], between the parts of each, that quick-silver (☿)(Hg) will NOT mix with: antimony (♁)(Sb), lead (♄)(Pb), or iron (♂)(Fe); and by a weak attraction, that quick-silver (☿)(Hg) and copper (♀)(Cu) WILL mix, with difficult; and from a strong attraction, that quicksilver (☿)(Hg) WILL mix readily with tin ( ♃)(Sn)?”
Isaac Newton (1718), “Query 31

“The will of the copper, claimed and preoccupied by the electrical opposition to the iron, leaves unused the opportunity that presents itself for its chemical affinity for oxygen and carbonic acid, behaves exactly as the will does in a person who abstains from an action to which he would otherwise feel moved, in order to perform another to which he is urged by a stronger motive.”
Arthur Schopenhauer (1844), The World as Will and Representation

“If iron sulphate and caustic potash are brought together, the SO4 ions leave the iron to unite with the potassium. When in nature an adjustment of such differences of potential is about to take place, he who would approve or disapprove of the process form the moral point of view would appear to most to play a ridiculous part.”
Otto Weininger (1903), Eros and Psyche

“Men believe that death is stronger than life, and therefore dead things must be stronger than living things; whether those dead things are gold and iron and machinery or rocks and rivers and forces of nature. It may sound fanciful to say that men we meet at tea tables or talk to at garden-parties are secretly worshippers of Baal or Moloch. But this sort of commercial mind has its own cosmic vision and it is the vision of Carthage. It has in it the brutal blunder that was the ruin of Carthage. The Punic power fell, because there is in this materialism a mad indifference to real thought. By disbelieving in the soul, it comes to disbelieving in the mind.”
— Gilbert Chesterton (1925), The Everlasting Man [2]
