An enzyme unit is micromol of substratate consumed (or product fomed) per unit time per mg protein.

Amit Kumar Mishra

Dear Hamed,

Here are the units for your query:

CAT- mM H2O2 decomposed per min; SOD- Unit per gram, POD- μmol purpurogallin

formed per min per g; APX- μmol per min per g; GR- μmol per min per g

You can go through the attached Paper for more details. I hope this information helps.

Arnab Mukherjee

μmol/mg protein..
