Iron (C0302583)

Definition (MSH) A metallic element with atomic symbol Fe, atomic number 26, and atomic weight 55.85. It is an essential constituent of HEMOGLOBINS; CYTOCHROMES; and IRON-BINDING PROTEINS. It plays a role in cellular redox reactions and in the transport of OXYGEN.
Definition (MEDLINEPLUS)

Iron is a mineral that our bodies need for many functions. The body needs iron to make the proteins hemoglobin and myoglobin. Hemoglobin is found in red blood cells and myoglobin is found in muscles. They help carry and store oxygen in the body. Iron is also part of many other proteins and enzymes in the body.

Your body needs the right amount of iron. If you have too little iron, you may develop iron deficiency anemia. Causes of low iron levels include blood loss, poor diet, or an inability to absorb enough iron from foods.

Too much iron is toxic to your body. Taking too many iron supplements can cause iron poisoning. Some people have an inherited disease called hemochromatosis. It causes too much iron to build up in the body.

Definition (NCI_NCI-GLOSS) An important mineral the body needs to make hemoglobin, a substance in the blood that carries oxygen from the lungs to tissues throughout the body. Iron is also an important part of many other proteins and enzymes needed by the body for normal growth and development. It is found in red meat, fish, poultry, lentils, beans, and foods with iron added, such as cereal.
Definition (NCI) An element with atomic symbol Fe, atomic number 26, and atomic weight 55.85.
Definition (CSP) metallic element found in certain minerals, in nearly all soils, and in mineral waters; atomic symbol Fe, atomic number 26, and atomic weight 55.85; it is an essential constituent of hemoglobin, cytochrome, and other components of respiratory enzyme systems; chief function is in the transport of oxygen to tissue (hemoglobin) and in cellular oxidation mechanisms.
Definition (PDQ) An element with atomic symbol Fe, atomic number 26, and atomic weight 55.85.
