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.
Bromelain extract is a mixture of protein-digesting (proteolytic) enzymes and several other substances in smaller quantities. The proteolytic enzymes are sulfhydryl proteases; a free sulfhydryl group of a cysteine amino acid side chain is required for function. The two main enzymes are: Stem bromelain - EC 3.4.22.32.
