Dissociation constant biochemistry
Webof time in ligand binding by macromolecules in the context of a general biochemistry course. Keywords: Ligand binding, dissociation constant, time, protein-ligand complex. Ligand binding is a key topic in the framework of a general biochemistry course; in fact, a characteristic prop-erty of nearly all proteins is their ability to bind specifically WebDissociation in chemistry is a general process in which molecules (or ionic compounds such as salts, or complexes) separate or split into other things such as atoms, ions, or radicals, usually in a reversible manner.For instance, when an acid dissolves in water, a covalent bond between an electronegative atom and a hydrogen atom is broken by …
