The subunits of hemoglobin are arranged in a tetrahedral array with a tight spehiracl overall appearance and each individual polypeptide is folded in such a manner to maximize POLAR residues being on the exposed surface and NONPOLAR intrracinte being internal, making this large protein water soluble.

Hemoglobin consist of 2 subunits, a and b differing in length of the polypeptide chain. The arrangement of polypeptide is made in such a manner so that POLAR residues present are exposed on outer surface so that it can dissolve in water as water is also polar . And NONPOLAR residues are kept inside so that it can cannot affect the solubility of protein in water.

Fetal hemoglobin consists of two alpha subunits and two gamma subunits. The gamma subunits have different residues at the 2,3-BPG binding site compared to those found in the beta subunits.

Fetal hemoglobin consists of two alpha subunits and two gamma subunits. The gamma subunits have different residues at the 2,3-BPG binding site compared to those found in the beta subunits. The charge characteristics of the different residues that are found in the gamma subunits allow for weaker binding to 2,3-BPG versus that seen in the case of adult hemoglobin, which contains two alpha subunits and two beta subunits. The statement is false. The statement is true.
