Ultimate Guide To Kats: History, Nutrition, And Recipes

What is a "kat"?

A "kat" is a unit of catalytic activity. It is defined as the amount of enzyme that catalyzes the conversion of one mole of substrate per second under specified conditions.

Kats are used to measure the activity of enzymes and to compare the activities of different enzymes. They are also used to calculate the amount of enzyme needed to carry out a specific reaction.

The kat is a relatively new unit of measurement. It was introduced in 1999 by the International Union of Pure and Applied Chemistry (IUPAC). The kat is named after the Greek word for "down", which refers to the fact that enzymes catalyze reactions by lowering the activation energy of the reaction.

Kats are an important tool for biochemists and other scientists who study enzymes. They allow scientists to compare the activities of different enzymes and to calculate the amount of enzyme needed to carry out a specific reaction.
