Key Equations

$$\text{Amino Acid}_1 + \text{Amino Acid}_2 \rightarrow \text{Dipeptide} + \text{H}_2\text{O}$$
$$\Delta G_{\text{total}} \approx -4 \times \Delta G°'_{\text{GTP hydrolysis}} \approx 4 \times (-30.5 \text{ kJ/mol}) = -122 \text{ kJ/mol}$$
$$\Delta G^\ddagger_{\omega} \approx 80 \text{ kJ/mol}$$
$$M_r \approx 110 \times 141 = 15{,}510 \text{ Da} \approx 15.5 \text{ kDa}$$

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