Cofactors can be divided into two major groups: organic cofactors, such as flavin or heme; and inorganic cofactors, such as the metal ions Mg 2+, Zn 2+, Cu +, Mn 2+ and iron–sulfur clusters.

In general, cofactors participate directly in biochemical reactions. In particular, they assist in the transfer of atoms, electrons, or functional groups between molecules. They may also facilitate substrate …

Apr 27, 2017 · Cofactors generally serve the purpose of supplying chemical groups or properties that are not found in other chemical groups. ATP, for example, is a cofactor with a unique ability to transfer …

There are two types of cofactors: inorganic ions [e.g., zinc or Cu (I) ions, also known as minerals] and organic molecules known as coenzymes. Most coenzymes are vitamins or are derived from vitamins.

Apr 29, 2025 · Explore the essential roles and mechanisms of cofactors in enzymes, highlighting their impact on enzyme activity and functionality.

Jul 23, 2025 · Cofactors are non-protein chemical compounds or metallic ions that are essential for an enzyme's biological activity. They can be organic molecules, called coenzymes, or inorganic ions.

Biochemists call these components “cofactors,” which include metal ions as well as “coenzymes,” which refers to cosubstrates and prosthetic groups. Each type of cofactor helps chemically modify a …

Cofactors are non-protein chemical compounds that assist enzymes in catalyzing biochemical reactions. They can be metal ions, like zinc or magnesium, or organic molecules, known as coenzymes, such …

Jun 17, 2025 · Cofactors are non-protein molecules that assist enzymes in catalyzing biochemical reactions. They can be broadly classified into three categories: metal ions, coenzymes, and …

This page provides an in-depth look at the function of cofactors in enzyme-catalyzed reactions, emphasizing their role in facilitating electron flow during chemical transformations.
