The haemoglobin of a human foetus

Step-by-step solution

Haemoglobin is the protein that makes red blood corpuscles red and binds easily and reversibly with oxygen. Normal values for haemoglobin are 14-20 ~g / 100 ~mL of blood in infants, 13-18 ~g / 100 ~mL in adult male and 12-16 ~g / 100 ~mL in adult females. Haemoglobin is made up of protein globin bound to the red haem pigment. The globin consists of four polypeptide chains-2 alpha and 2 beta. Foetal haemoglobin does not sickle even in those distined to have sickle cell anaemia, i e , haemoglobin of foetus has higher
