Proteins blood cells carries the oxygen and transfer into lungs to tissue and organs. Abnormalities level or structure leads the problem of serious symptoms.
Symptoms of Haemoglobin in blood test :
Fatigue
Rapid

Protein structure is made up of four amino acids. i.e. an amino (NH2) group, a carboxyl (COOH) group, a hydrogen (H) atom, and one variable group. These four chain contains iron, transports oxygen in the blood stream.
Structure of Haemoglobin in blood test :

α- subunit : made up of alpha polypeptide chain. It having 141 amino acids residues.
β-subunit : made up of bita polypeptide chain. It having 146 amino acid residues.
Heme group : Heme group contains the prosthetic group. It is attached to polypeptide chain. Heme group contains iron. It is situated in centre of porphyria ring.
Haemoglobin responsible of shape of RBCs. It is appear like donuts – but with a thin centre than a hole. Abnormal haemoglobin involve sickle cell Anemia. Abnormal shape of RBCs is most dangerous which can lead to problem.
