Difference between Cofactor and Coenzyme

Main Difference

A substance that becomes essential for the working of an enzyme and carrying out its processes other than the substrate becomes known as a cofactor. On the other hand, a substance that becomes essential for the working and function of an enzyme other than the protein compounds becomes known as a coenzyme.

Cofactor

A substance that becomes essential for the working of an enzyme and carrying out its processes other than the substrate becomes known as a cofactor. Cofactors can get subclassified as either inorganic particles or complex natural atoms called coenzymes, the last of which for the most part gets from vitamins and other natural essential supplements in small sums. A coenzyme that is firmly or even covalently bound is named a prosthetic gathering. The first sort of compound accomplice is a collection called cofactors, or particles that expansion the rate of response or required for protein work. Cofactors are not proteins yet rather help proteins, for example, chemicals, even though they can help non-compound proteins also. Cases of cofactors incorporate metal particles like iron and zinc. Substrates are momentarily bound to the protein and will get discharged sooner or later, then get back in. The prosthetic gatherings, then again, are connected for all time to the protein. The two have a similar capacity, which is to encourage the response of chemicals and protein. Furthermore, a few sources likewise confine the utilization of the expression “cofactor” to inorganic substances. Natural cofactors are frequently vitamins or produced using vitamins. Many contain the nucleotide adenosine monophosphate (AMP) as a component of their structures, for example, ATP, coenzyme A, FAD, and NAD+.

Coenzyme

A substance that becomes essential for the working and function of an enzyme other than the protein compounds becomes known as a coenzyme. Coenzymes regularly work as the middle of the road bearers of electrons, molecules or practical gatherings that transfer in the general response. A case of this would be the part of NAD in the move of electrons in certainly coupled oxidation diminishment responses. A coenzyme is a substance that works with a compound to start or help the capacity of the protein. It might get viewed as an assistant particle for a biochemical response. Coenzymes are tiny, non-proteinaceous particles that give an exchange site to a working catalyst. They are moderate bearers of an iota or gathering of particles, enabling a response to happen. Coenzymes don’t get considered some portion of a protein’s structure; they here and there alluded to as substrates. A sort of cofactor, coenzymes, are fundamental particles that dilemma to compounds and help them work. The key here is that they’re natural. “Natural” does not mean you’ll see them in a unique walkway in the market. Or maybe, fundamental particles are substantially atoms that contain carbon. Try not to give the name “coenzymes” a chance to trick you, either; coenzymes are not by any means proteins. As the prefix ‘co-” recommends, they work with proteins. Numerous coenzymes formed from vitamins. Coenzymes can’t work all alone and do require the nearness of a chemical. A few compounds require a few coenzymes and cofactors.

Key Differences

  • A substance that becomes essential for the working of an enzyme and carrying out its processes other than the substrate becomes known as a cofactor. On the other hand, a substance that becomes essential for the working and function of an enzyme other than the protein compounds becomes known as a coenzyme.
  • Coenzymes become the organic molecule that becomes the basis of the proper functioning of an enzyme that has different purposes within the cell. On the other hand, the cofactor becomes inorganic particles that become required for the proper enzyme functioning.
  • Some of the primary examples of coenzyme include NAD+, FAD+ and vitamin complexes. On the other hand, some of the prime examples of cofactors include copper, zinc, magnesium and potassium.
  • The key purpose of cofactors becomes to increase the speed at which the reaction takes place during the enzyme’s functioning. On the other hand, the chief purpose of coenzyme becomes to help the molecules that bind the protein to function properly.
  • Cofactors are compounds that help with the chemical reactions taking place within, on the other hand, coenzyme is synthetic molecules that perform the task assigned to them.
  • Cofactors get tightly bound with an enzyme, whereas coenzymes do not have to stay bounded with any other structure.
