Amylase /ˈæmɪleɪz/ is an enzyme that catalyses the breakdown of starch into sugars. Amylase is present in human saliva, where it begins the chemical process of digestion. Foods that contain much starch but little sugar, such as rice and potato, taste slightly sweet as they are chewed because amylase turns some of their starch into sugar in the mouth. The pancreas also makes amylase (alpha amylase) to hydrolyse dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy. Plants and some bacteria also produce amylase. As diastase, amylase was the first enzyme to be discovered and isolated (by Anselme Payen in 1833). Specific amylase proteins are designated by different Greek letters. All amylases are glycoside hydrolases and act on α-1,4-glycosidic bonds.
The α-amylases (EC 3.2.1.1 ) (CAS# 9014-71-5) (alternative names: 1,4-α-D-glucan glucanohydrolase; glycogenase)are calcium metalloenzymes, completely unable to function in the absence of calcium. By acting at random locations along the starch chain, α-amylase breaks down long-chain carbohydrates, ultimately yielding maltotriose and maltose from amylose, or maltose, glucose and "limit dextrin" from amylopectin. Because it can act anywhere on the substrate, α-amylase tends to be faster-acting than β-amylase. In animals, it is a major digestive enzyme, and its optimum pH is 6.7-7.0.

Let's not forget, lets not forget what happened in the past,
You were right, you were wrong, yeah but everything was fast,
So when we build this ship remember to make it last,
Increase the time it takes to paint and build the mast,
Lets save this game for never,
Or you know this could be chess forever,
I'll take your piece,
Then you'll take mine,
Stalemate and we've just wasted time,
Yeah the past's the route of the growing that happens now,
So lets remember not to turn on straight to a row,
We can see through the haze of misty glaze,
So now lets travel positively forward through the maze,
Lets save this game for never,
Or you know this could be chess forever,
I'll take your piece,
Then you'll take mine,
Stalemate and we've just wasted time,
We've just wasted time,
We've just wasted time,
We need a catalyst,
We need a catalyst,
We'll swim through the fields of hay, (x4)
You're the catalyst that makes things faster,
