why iron is important for body?

WHY IRON MUST IN DIET?WHAT IT'S IMPORTANCE

                                               
                   

iron(Fe) is mineral present in body mainly provided as supplement for body.Iiron is trace or  Micro minerals,trace minerals are those minerals that are pesent in low concentration (<70 mg/kg live weight) but are physiologically equally important to major minerals in body.

IMOPRTANCE OF IRON IN BODY

• Formation of haemoglobin(iron binding protein)
  
  
  
  
  

MORE than 90 per cent of the iron in the body is combined with proteins, the most important being haemoglobin(oxygen carrying pigment) and myoglobin.

• TRANSFERRIN
  

iron also occurs in blood serum in a protein called transferrin, which is concerned with the transport of iron from one part of the body to another.

• FERRETIN 
  

Ferritin is a protein containing iron. It is present in the spleen, liver, kidney and bone marrow and provides a form of storage for iron.

• BIOCHEMICAL REACTIONS
  

Iron has a major role in many of biochemical reactions, particularly in connection with enzymes of the electron transport chain (cytochromes).

• ENZYMES FORMATIONS
  

various enzymes contain iron as prosthetic group or activated by iron.examples catalase, peroxidases, phenylalanine hydroxylase etc

• DEFICIENCY OF IRON
  
  

Anaemia due to iron deficiency occurs most commonly in young one deprived from supplement, since the iron content of milk is usually very low.

Low oxygen to organ due to less RBC formations in body.
