Hill equation

The Hill equation describes how a substance, like a drug or hormone, binds to a target, such as a receptor, often influencing its activity. It characterizes the relationship between the amount of the substance and the response produced. The equation accounts for situations where multiple binding sites work together cooperatively—meaning the binding of one molecule affects others. This helps scientists understand how strongly and efficiently the substance interacts with its target, providing insights into drug effectiveness and receptor behavior in biological systems.
