Biochemistry

Michaelis enzyme kinetics

v=\frac{V_{\max}[S]}{K_m+[S]}

describes the relationship between the initial velocity of a single substrate enzymatic reaction and the substrate concentration.

Biochemistry

\theta=\frac{[L]^n}{K_d^n+[L]^n}

describes binding site occupancy using empirical cooperativity parameters.

Biochemistry

\mathrm{pH}=\mathrm pK_a+\log_{10}\frac{[A^-]}{[HA]}

estimates the ratio of weak acid to conjugate base in a buffer system.

Biochemistry

v=\frac{V_{\max}[S]}{K_m(1+[I]/K_i)+[S]}

describes the effect of a competitive inhibitor that increases the apparent Michaelis constant.
