Coenzymes


Coenzymes are not used up in the reactions in which they assist (for example: a coenzyme may act as a reduction/oxidation agent or agent of a similar transfer).

coenzymes - Small molecule tightly associated with an enzyme that participates in the reaction that the enzyme catalyzes, often by forming a transient covalent bond to the
substrate.

Coenzymes may be covalently bound to the protein part (called the apoenzyme) of enzymes as a prosthetic group. Others bind more loosely and, in fact, may bind only transiently to the enzyme as it performs its catalytic act.

coenzymes: organic molecules that act as cofactors, such as NAD and FAD.
cofactors: ions or molecules that associate with enzymes and are required for enzymatic reactions to take place.

Coenzymes
Many enzymes require a cofactor to assist in the reaction. These "assistants" are nonprotein and may be metal ions such as magnesium (Mg++), potassium (K+), and calcium (Ca++).
