The International Union of Biochemistry and Molecular Biology (IUBMB) is the international umbrella organization for societies in the fields of biochemistry and molecular biology. It brings together national societies from numerous countries and regions around the world.
The IUBMB’s mission is to support research and education in biochemistry and molecular biology on a global scale, to strengthen international collaboration, and to promote the next generation of scientists, particularly in regions with fewer resources.

A key area of focus for the IUBMB is the development and maintenance of internationally recognized standards, such as those for enzyme and biochemical nomenclature.
