Low ph trypsin
WebEnzyme-catalysed hydrolysis is important in protein digestion. Protein hydrolysis is initiated by pepsin at low pH in the stomach. However, pepsin action and acidification happen … Web10 apr. 2024 · Immobilization of trypsin was performed as follows. First, potato-starch gel was prepared by boiling starch suspension for 2 min and cooling to 25 °C. Next, the trypsin solution was mixed with potato-starch gel, and 25-μL drops were placed onto fluoropolymer film and dried at 8 °C.
