Unit Information

Enzyme Unit (U)

Definition: A unit of enzyme activity equal to 1 μmol of substrate converted per minute.

History: Traditional unit used before the adoption of the katal.

Current Use: Still widely used in biochemistry and diagnostics.

Katal (kat)

Definition: The SI unit of catalytic activity, equal to one mole of substrate converted per second.

History: Adopted as SI unit in 1999.

Current Use: Standard unit for catalytic activity in scientific applications.

Millikatal (mkat)

Definition: A unit of catalytic activity equal to one thousandth of a katal (10⁻³ kat).

History: Common engineering and lab unit.

Current Use: Used in clinical chemistry and biochemistry.

Kilokatal (kkat)

Definition: A unit of catalytic activity equal to one thousand katals (10³ kat).

History: Used to express very high enzyme activities.

Current Use: Industrial enzymology and large-scale processes.

Millienzyme unit (mU)

Definition: A unit equal to 10⁻³ enzyme units (mU).

History: Common in clinical diagnostics.

Current Use: Reporting enzyme levels in lab tests.

Microenzyme unit (μU)

Definition: A unit equal to 10⁻⁶ enzyme units (μU).

History: Used for very low enzyme concentrations.

Current Use: Sensitive enzyme assays.

Nanoenzyme unit (nU)

Definition: A unit equal to 10⁻⁹ enzyme units (nU).

History: Used for extremely low activities.

Current Use: Specialized research applications.

Kiloenzyme unit (kU)

Definition: A unit equal to 10³ enzyme units (kU).

History: Used for bulk enzyme quantities.

Current Use: Biotechnology and industry.

Megaenzyme unit (MU)

Definition: A unit equal to 10⁶ enzyme units (MU).

History: Used for very large quantities of enzymes.

Current Use: Industrial applications.

International Unit (IU) (IU)

Definition: Alias of the enzyme unit (U), equal to the amount of enzyme that catalyzes 1 micromole of substrate per minute.

History: Widely used in clinical and research labs as an alternative notation to U.

Current Use: Interchangeable with U in reports and specifications.
