Cofactor vs Coenzyme: Difference and Comparison

Various kinds of enzymes and factors function in our bodies. Living Beings health depended on their functions. There are a few things that vary between Cofactor and Coenzyme.

A cofactor is a kind of chemical component with non-protein that does not tie up with an enzyme, whereas a Coenzyme is a component that acts as a catalyst on an Enzyme. The cofactors and coenzymes help to function biochemically. Some of the facts and differences between Cofactor and Coenzyme had listed below.  

Key Takeaways

  1. Cofactors are non-protein, inorganic molecules or ions that assist enzyme function, while coenzymes are organic molecules that help enzymes catalyze reactions.
  2. Cofactors can be either metal ions or small organic molecules, whereas coenzymes are derived from vitamins.
  3. Cofactors may be tightly or loosely bound to enzymes, while coenzymes form temporary, non-covalent bonds.

Cofactor vs Coenzyme  

Cofactors are essential for enzyme activity, and a deficiency can lead to enzyme dysfunction and disease. Coenzymes are organic cofactors derived from vitamins that are needed for the activity of enzymes. They are not permanently bound to enzymes but are temporarily associated with them during catalysis.

A cofactor is a chemical component catalyst that plays a catalyst role in enzymes. The cofactors do not hold together with the enzymes. Cofactors are known as helper molecules, where the biochemical transformations work on these. The study of these characterized functions in an area called Enzyme Kinetics.  

In Contrast, Coenzyme is a chemical component that holds together with the Enzymes in a function. These are non-protein compounds that support the enzymes. These Coenzymes help to occur chemical reactions which had carried out by an enzyme. Although these are non-protein compounds, they can involve in chemical reactions. The Coenzymes will tie up with the shape and structure of the enzymes.  

Comparison Table

Parameters of Comparison Cofactor Coenzyme  
Meaning The cofactor is a chemical component that acts as a catalyst on an enzyme. Coenzyme is a chemical compound that had used to support the enzymes. 
Function Its function is to help the active enzymes. It supports the enzymes in a chemical reaction. 
Difference Cofactors are not held together with the enzymes. These had tied up with the enzymes according to their structure.  
Occurrence   Cofactors are of two types:  Organic and inorganic molecules. The organic molecules of the cofactors are known as Coenzymes. 
Categories These had categorized as Metal Ions, Coenzymes and Prosthetics Groups. The kinds in Coenzymes are Prosthetics Groups and Cosubstrates.  

What is Cofactor?  

The cofactor is a kind of chemical component with non-protein that does not tie up with the enzyme. These cofactors are present in enzymes but do not bind with them. Its function is to help the active enzymes. The Cofactor acts as a catalyst for functioning the active enzymes. These are metallic ions known as helper molecules in biochemical conversions. The principal function of the Cofactor is to help the function of the enzyme. The study of these characterized functions in an area called Enzyme Kinetics. The organic molecules of the cofactors are known as coenzymes. Cofactors are sundered into two kinds, they are  

  • Organic molecules  
  • Inorganic ions

These organic molecules are the coenzymes that tie up with the enzymes. Examples of inorganic ions are copper, zinc and some others. However, coenzymes have their functions. The Cofactors were classified into three categories: Metal Ions, Coenzymes and Prosthetics Groups. The enzymes cannot perform the functions alone where the help of a cofactor had used for discharge. The division of the cofactors into small metallic organic ions are coenzymes that help in a chemical reaction. Although these are non-protein compounds, the functioning of cofactors is helpful in the body. Cofactors are not held together with the enzymes. The inorganic factors include the ions like magnesium, clusters of iron-sulfur, copper, and manganese, whereas the organic cofactors include flavin, heme, Prosthetics and coenzymes.

What is Coenzyme?  

Coenzyme is a component that acts as a catalyst in Enzymes. The Coenzymes are held together with the enzymes according to their shapes and structure. These are the organic molecules of cofactors and assembled from the vitamins.

The primary function of the Coenzymes is to support and help the enzymes in chemical reactions. By binding on the active enzymes, these coenzymes had involved in the chemical reactions. Although these are non-protein compounds, they can require in chemical reactions. The kinds of Coenzymes are  

  • Prosthetic groups  
  • Co-Substrates  

The Coenzymes will assist in the substrate recruitment of the enzyme on active sites. Some examples of Coenzymes are  

The above examples of the Coenzymes help to perform oxidation which is to transfer the hydrogen. The coenzymes do not perform any chemical reactions themselves because these are tiny molecules. By binding with the protein enzymes, they can use to perform the chemical reaction between molecules.

Main Differences Between Cofactor and Coenzyme  

  1. A cofactor is the chemical composition of the enzymes, whereas coenzymes had produced from vitamins that act on the enzymes.  
  2. Cofactor divides into organic and inorganic ions where the organic molecules of the Cofactor are Coenzymes.  
  3. A cofactor had used to help the active enzymes, whereas Coenzyme had used to perform the chemical reaction with the help of an enzyme.   
  4. Cofactor does not hold together on the enzymes, whereas Coenzyme ties up with the shape and structure of the enzymes.  
  5. Cofactors were categorized into three groups, whereas the Coenzymes were classified into two groups.
