Hill's Equation

Hill's Equation describes how the rate of a chemical reaction or biological process responds to varying levels of a controlling factor, like a hormone or drug, often used in pharmacology. It expresses the relationship between the concentration of the substance and the observed effect, typically showing a sigmoidal (S-shaped) curve. The equation helps determine how sensitive an system is to the substance and at what concentration half of the maximum effect occurs, called the EC50. This model is useful for understanding dose-response relationships and designing optimal therapeutic doses, reflecting effects across different concentration levels.
