A variant of hemoglobin (Boston variant; mutation His E7(58)α → Tyr) promotes methemoglobin formation involving the α (alpha) subunits. What is the maximum value of the Hill constant (n) that you could measure for the Boston variant of hemoglobin?   log (YO2 / 1 - YO2 ) = log pO2 - logP50 Please break down each step of the Hill equation and explain why the result for n is valid from a logical standpoint.
