Question

Quizplus · Accepted Answer

The space between the helices in hemoglobin is hydrophobic in nature, and hence a hydrophobic amino acid residue would fit in most efficiently and tightly, as it would interact favorably with the surrounding hydrophobic environment. Polar, acidic, or basic residues may not interact as favorably with this environment and may not fit as tightly.
