A microkatal 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 microkatals per liter
