Key Equations

$$\text{H}_2\text{N} - \underset{\displaystyle |}{\overset{\displaystyle \text{R}}{\text{C}}} \text{H} - \text{COOH}$$
$$\text{pH} - \text{p}K_a = 3.34 - 2.34 = 1.00 \implies \frac{[\text{COO}^-]}{[\text{COOH}]} = 10^1 = 10$$
$$\text{pI} = \frac{\text{p}K_{a1} + \text{p}K_{aR}}{2} = \frac{2.09 + 3.86}{2} = 2.98$$
$$\text{pI}_{\text{Glu}} = \frac{\text{p}K_{a1} + \text{p}K_{aR}}{2} = \frac{2.19 + 4.25}{2} = 3.22$$

Equations are rendered with MathJax in the PDF with professional LaTeX typesetting.
