Basic concepts
cofactor
（1） Enzymaticcoenzyme、CofactorOr metal ions.They andEnzyme proteinAfter combination, the enzyme can have catalytic activity, otherwise it has no catalytic activity.
（3） In a broad sense, where can promote enzyme andreactantEnter the active state to accelerateEnzyme catalyzed reactionAll the substances can be called cofactors, which include a wide range of substances.The English Chinese Biochemical Dictionary defines cofactors as "a nonproteinComposition ".This cofactor may be a metal ion activator or aOrganic molecule(coenzyme).They either loosely or tightly combine with enzymes;The closely joined cofactors are called "cofactors".takeactivator（activator）Defined as "a metal ion, as aCofactor of enzyme”。
