Airsoft guns can be modified to increase pellet velocity, rate of fire, reliability, or accuracy/range. For an electric airsoft gun, the pellet velocity can be increased by two different methods. The first is upgrading the inner barrel of the gun.
In this juice are enzymes (including lipase, protease, and amylase) required for the digestion and absorption of food. Lipase (along with bile) helps digest fats. Amylase (secreted by the salivary glands and pancreas) breaks down starch molecules into more absorbable sugars. The proteases secreted by the pancreas (trypsin, chymotrypsin, and carboxypeptidase) break protein molecules into single amino acids.
1 Amylase catalyses the breakdown of starch into sugars in the mouth and small intestine. 2  Proteases catalyse the breakdown of proteins into amino acids in the stomach and small intestine. 3  Lipases catalyse the breakdown of fats and oils into fatty acids and glycerol in the small intestine.
