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)
