Wheat proteins account for 10–15% of dry weight. They are classified based on the soluble property in a solvent. The two main groups of wheat allergens are the salt-soluble fraction, composed of the alpha-amylase/trypsin inhibitor subunit, and the salt-insoluble fraction, called the gluten fraction.

Webtrypsin enzyme experiment - Example. Trypsin is a proteolytic enzyme that is produced by the pancreas and is responsible for breaking down proteins in the small intestine. It is able to cleave peptide bonds at the carboxyl end of lysine and arginine residues, making it an important enzyme in the digestion of proteins. WebBackground: As you know from reviewing the Pepsin Report, pepsin is an enzyme that hydrolyzes the peptide bond of a substrate. As a result, the protein is cleaved into smaller units. The reaction (as is most enzyme reactions) is pH dependent. It is the purpose of this experiment to investigate the pH dependence of the pepsin reaction.
