Important Equation of Biomolecules

1. Henderson-Hasselbalch Equation:

$\text{pH} = \text{pKa} + \log\left(\frac{[\text{A}^-]}{[\text{HA}]}\right)$

This equation relates the pH of a solution to the pKa of an acidic substance and the ratio of its conjugate base $(A^-)$ to the undissociated acid (HA)


2. Michaelis-Menten Equation:

$v = \frac{{V_{\text{max}} \cdot [S]}}{{K_{\text{m}} + [S]}}$

This equation describes the rate of an enzyme-catalyzed reaction (v) as a function of the subtract concentration $([S])$, maximum reaction rate $(V_{max})$, and Michaelis constant $(K_{m})$


3. Nernst Equation:

$E = E^\circ - \frac{0.0591}{n} \cdot \log\left(\frac{[\text{Reductant}]}{[\text{Oxidant}]}\right)$


This equation relates the standard cell potential $(E^{\circ})$, actual cell potential (E), and the concentration of reductant and oxidant in an electrochemical cell.


4. Lineweaver-Burk Equation (Double Reciprocal Plot):

$\frac{1}{v} = \frac{K_{\text{m}}}{V_{\text{max}}} \cdot \frac{1}{[S]} + \frac{1}{V_{\text{max}}}$


This equation is another form of the Michaelis-Menten equation often used for the graphical representation and analysis of enzyme kinetics.


5. Gibbs Free Energy (\(\Delta G\)) and Equilibrium Constant (\(K\)) Relationship:

$\Delta G = -RT \cdot \ln(K)$

This equation relates the change in Gibbs free energy $(\Delta G)$ to the equilibrium constant (K), temperature (T), and the ideal gas constant (R)


6. Van't Hoff Factor (\(i\)) for Colligative Properties:

$i = \frac{\text{moles of particles formed}}{\text{moles of solute dissolved}}$

The Van't Hoff factor accounts for the number of particles produced when a solute dissolves, influencing colligative properties like osmotic pressure and freezing point depression.
