🧬 Computational Biology Fundamentals
Computational biology uses mathematical and computational methods to study biological systems and processes.
Reaction Rate
The rate of a biochemical reaction:
Rate = k × [A]^m × [B]^n
Where k is the rate constant, [A] and [B] are concentrations, and m, n are reaction orders.
Michaelis-Menten Kinetics
Enzyme kinetics equation:
v = (V_max × [S]) / (K_m + [S])
Where v is reaction velocity, V_max is maximum velocity, [S] is substrate concentration, and K_m is Michaelis constant.
Hill Equation
Cooperative binding equation:
Y = (L^n) / (K_d + L^n)
Where Y is fractional saturation, L is ligand concentration, n is Hill coefficient, and K_d is dissociation constant.
