Inhibitory concentration (IC)
Biology; Toxicology
Concentration of a substance that causes a defined inhibition of a given system. Note: IC50 is the median concentration that causes 50% inhibition.
Effective concentration (EC)
Biology; Toxicology
Concentration of a substance that causes a defined magnitude of response in a given system. Note: EC50 is the median concentration that causes 50 % of maximal response.
Partition coefficient
Biology; Toxicology
Concentration of a substance in one phase divided by the concentration of the substance in the other phase when the heterogeneous system of two phases is in equilibrium. Note 1: The ratio of ...
