There are millions of processes going on in a human body every second. It's amazing all the different types of enzymes in the human body alone you never even think about. Enzymes are a basic part of biology that helps sustain life.
Acyltransferase, Disaccharidase and Kinase are all different types of enzymes. Each one having its own specific duty to keep the biological machine running.
Enzymes were initially a big mystery. Everybody knew that somehow proteins were digested and starch would be turned into sugars, but the mechanism was not clear.
Diastase was the first enzyme discovered. It was isolated in a malt solution by two French chemists Anselme Payen and Jean-François Persoz. This discovery was the beginning of an understanding of one of the basic mechanisms of a biological body.
