"Enzyme activity is the amount substrate converted by the enzyme in moles per unit time. The SI unit of the enzymatic activity is katal, which is equal to mol S-1. However, this is a considerably large unit; hence, the most common unit used is the enzyme unit (U). 1U is equal to 1 μmol min−1. Especially, the katal … See more Specific activity is the activity of the enzyme per milligram of the total enzyme. It means that this measurement gives the purity of the enzyme in a mixture.
