Henderson Hasselbalch Equation
pH= pKa + log (base/acid)
Keq
([C]^c [D]^d) / ([A]^a[B]^b)
pH=
pH = -log [H+]
At equilibrium delta G=
0
Delta G, Entropy and Enthalpy Equation
Delta G= Delta H - T Delta S
Acid Dissociation Constant Ka
Ka= [H+][Base] / Acid
pKa
pKa= -log Ka
Relates Keq and Delta G not
Delta G not = -RT ln Keq
Relates Keq and Delta G and Delta G not
Delta G= Delta G not + RT ln Keq
How to Calculate Delta S Entropy
Delta S = Kb ln W
Kb= Boltzman constant, W= #of ways to arrange
Myoglobin Fractional Saturation % Y
Y = [Mb O2] / ( [MbO2] + [Mb] ) MbO2 = Oxygen bound to Myoglobin, Mb unbound Myoglobin
Myoglobin Fractional Saturation % Y Pressure in O
Y = pO2 / (pO2 + K)
Michaelis Menton Equation
v = Vmax [S] / ( Km + [S] )
2 unknowns Vmax and Km
Michaelis Menton Equation Competitive Inhibition
v = Vmax [S] / ( Alpha*Km + [S] )
Michaelis Menton Equation UnCompetitive Inhibition
v = Vmax [S] / ( Km + alpha prime [S] )
