Question

How to calculate esterase activity from pnpa reduction colorimetrically?

Answer 1

In this study, we show that measuring the esterase activity of carbonic enzymes at a fixed concentration (1mM) of pNPA substrate

Answer 2

Explanation:

All the halogens react directly with hydrogen, forming covalent bonds and—at sufficient levels of purity—colorless gases at room temperature. Hydrogen reacts with fluorine, chlorine, bromine, and iodine, forming HF, HCl, HBr, and HI, respectively.
