What are the units with which enzymes are measured?

When comparing enzyme products make sure enzyme activities are measured using units such as these:

 

  • Alpha-Galactosidase - GALU (Galactosidase Units)
  • Amylase - DU (Dextrinizing Units)
  • Bromelain - GDU (Gelatin Digesting Units) or FCCPU
  • Catalase - Baker Units (Named after the author)
  • Cellulase - CU (Cellulase Unit)
  • Glucoamylase - AGU (Amyloglucosidase Units)
  • Hemicellulase - HCU (Hemicellulase Units)
  • Invertase - INVU (Invertase Activity Unit) or SU (Sumner Units)
  • Lactase - ALU (Acid Lactase Unit)
  • Lipase - FCCFIP (Federation Internationale Pharmceutique)
  • Maltase - DP (Degrees of Diastatic Power)
  • Nattokinase - FU (Fibrinolytic Units)
  • Pectinase - Endo-PGU (Endo-Polygalacturonase Units)
  • Phytase - FTU (Phytase Units)
  • Protease-HUT (Hemoglobin Unit on a L-Tyrosine Basis)
  • Xylanase - XU (Xylanase Units)
