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.
The pancreas makes lipase to digest fats into fatty acids. Sugars and fatty acids can then be absorbed by the small intestine. Some amylase and lipase can also be found in saliva and in the stomach, but most of it is made in the pancreas and released into the small intestine. In a healthy individual, a normal blood amylase level is 23-85 units per liter, (U/L).
