Question: 1 katal is equal to how many iu?
Answer: The SI unit of enzyme catalytic activity is the katal, however, it is less commonly used in practice. 1 katal = amount of enzyme that catalyzes the conversion of 1 mole of substrate per second (1 katal = 1 mol/s). Thus, 1 Unit = 1.667 × 10-8 katal and 1 katal = 6.00 × 107 Units.
