Hint: First we have to know that haemoglobin is a protein molecule present in red blood cells. The molecular formula is a chemical formula consisting of the chemical symbols for the elements followed by numeric subscripts describing the number of atoms of each element present in the molecule.
Complete answer:
Haemoglobin carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. Since iron present in haemoglobin is also responsible for the red colour of blood. So, it is a red pigment in blood and it consists of a protein component and the iron complex of a porphyrin derivative. Its molecular weight is \[1450.7\].
The molecular formula of haemoglobin is \[{C_{2952}}{H_{4664}}{N_{812}}{O_{832}}{S_8}F{e_4}\].
Additional information: The common types of normal haemoglobin are Haemoglobin \[A\], Haemoglobin \[F\], Haemoglobin \[A2\].
Haemoglobin \[A\] is found normally in adults. Haemoglobin \[F\] is normally found in fetuses and newborn babies. Whereas haemoglobin \[A2\] is found in small amounts in adults.
Low haemoglobin level is an indication of anaemia. The main symptoms of low haemoglobin are weakness, pale or yellow skin, chest pain, etc.
Note:
Haemoglobin is composed of four different protein molecules. The protein molecules are four polypeptide chains \[{\alpha _1},{\alpha _2},{\beta _1},\] and \[{\beta _2}\]. Each chain is attached to a heme group (A group contains ion molecules having a prosthetic group) composed of porphyrin attached to an iron atom.
