What are microkats per liter (mckat/L)?

A microkat is a unit of measurement used in chemistry to describe enzyme reactions. A catalyst starts or speeds up a chemical reaction. Enzymes are proteins that act as catalysts in the body. A catalyst measures one katal if it causes a chemical reaction at one mole per second. A liter is a measure of volume that is a little more than a quart.

Some medical tests report results using microkats per liter (mckat/L).
