What's the difference between hemoglobin and iron?

Hemoglobin


Definition:

  • (n.) The normal coloring matter of the red blood corpuscles of vertebrate animals. It is composed of hematin and globulin, and is also called haematoglobulin. In arterial blood, it is always combined with oxygen, and is then called oxyhemoglobin. It crystallizes under different forms from different animals, and when crystallized, is called haematocrystallin. See Blood crystal, under Blood.

Iron


Definition:

  • (n.) The most common and most useful metallic element, being of almost universal occurrence, usually in the form of an oxide (as hematite, magnetite, etc.), or a hydrous oxide (as limonite, turgite, etc.). It is reduced on an enormous scale in three principal forms; viz., cast iron, steel, and wrought iron. Iron usually appears dark brown, from oxidation or impurity, but when pure, or on a fresh surface, is a gray or white metal. It is easily oxidized (rusted) by moisture, and is attacked by many corrosive agents. Symbol Fe (Latin Ferrum). Atomic weight 55.9. Specific gravity, pure iron, 7.86; cast iron, 7.1. In magnetic properties, it is superior to all other substances.
  • (n.) An instrument or utensil made of iron; -- chiefly in composition; as, a flatiron, a smoothing iron, etc.
  • (n.) Fetters; chains; handcuffs; manacles.
  • (n.) Strength; power; firmness; inflexibility; as, to rule with a rod of iron.

  • (n.) Rude; hard; harsh; severe.
  • (n.) Firm; robust; enduring; as, an iron constitution.
  • (n.) Inflexible; unrelenting; as, an iron will.
  • (n.) Not to be broken; holding or binding fast; tenacious.
