Haemoglobin in adult humans represent which structure of the protein?\

Question

Professor PC Thomas Classes · Answer

(d) : SomeProteins are an assembly of more than one polypeptide or subunits. The manner in which these individual folded polypeptides or subunits are arranged with respect to each other is the architecture of a protein called the quaternary structure of a protein. Adult human haemoglobin consists of 4 subunits and have quaternary structure. Two of these are identical to each other. Hence, two subunits of $\alpha$ type and two subunits of $\beta$ type together constitute the human haemoglobin (Hb).
