Receptor site theory definition chemistry
Webb3 apr. 2008 · Receptor is a macromolecule in the membrane or inside the cell that specifically (chemically) bind a ligand (drug). The binding of a drug to receptor depends on types of chemical bounds that can be established between drug and receptor. WebbReceptors are saturable binding sites that express an effect. The law of mass action describes the equilibrium between association and dissociation of ligands with binding sites. Binding site + Cu ←→ Cb-Binding site i.e. Unbound Receptor + Unbound Drug ←→ Receptor-Drug Complex

The effect of a drug present at the site of action is determined by that drug’s binding with a receptor. Receptors may be present on neurons in the central nervous system (i.e., opiate receptors) to
WebbThe nervous system is composed of more than 100 billion cells known as neurons. A neuron is a cell in the nervous system whose function it is to receive and transmit information (see Figure 3.1 ). Neurons are made up of three major parts: a cell body, or soma, which contains the nucleus of the cell and keeps the cell alive; a branching treelike … Webb28 dec. 2024 · The main points to describe receptor theory are: Drugs interact with receptors in a reversible manner to produce a change in the state of the receptor. This interaction can be modeled mathematically and follows the Law of Mass Action. The binding of drug and receptor determines the quantitative relationship between dose and …
