Key Equations

$$\text{Acetyl-CoA} + 3\,\text{NAD}^+ + \text{FAD} + \text{GDP} + \text{P}_i + 2\,\text{H}_2\text{O} \;\longrightarrow\; \text{CoA-SH} + 3\,\text{NADH} + \text{FADH}_2 + \text{GTP} + 2\,\text{CO}_2$$
$$\text{Acetyl-CoA} + \text{OAA} + \text{H}_2\text{O} \rightarrow \text{Citrate} + \text{CoA-SH} \qquad \Delta G^{\circ\prime} = -31.4\;\text{kJ/mol}$$
$$\text{Isocitrate} + \text{NAD}^+ \rightarrow \alpha\text{-Ketoglutarate} + \text{CO}_2 + \text{NADH} \qquad \Delta G^{\circ\prime} = -20.9\;\text{kJ/mol}$$
$$\text{Succinyl-CoA} + \text{GDP} + \text{P}_i \rightarrow \text{Succinate} + \text{CoA-SH} + \text{GTP} \qquad \Delta G^{\circ\prime} = -2.9\;\text{kJ/mol}$$

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