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.
Amylase is an enzyme that has several different forms called isoenzymes. Different tissues make different forms. P-amylase refers to the type of amylase made mainly in the pancreas. S-amylase refers to the type of amylase made mainly by the salivary glands. P-amylase in the blood increases when the pancreas is inflamed or damaged. S-amylase in the blood increases when the salivary gland is inflamed or damaged.
