Webb8 apr. 2024 · Views today: 2.94k. Maltase is defined as an enzyme that catalyzes the disaccharide maltose hydrolysis to the simple sugar glucose. This enzyme is present in bacteria, yeast, and plants, and it is thought to be generated by cells of the mucous membrane lining the intestinal wall in humans and other vertebrates. Webbacid caused a slower reaction of protein termination resulting in an increase in the casein yield. The casein yield value decreased at 60 minutes due to the protein matrix termination reaction so that more water came out. However, casein yield value re-increased at 90 minutes due to the re-absorption of water content in the protein matrix. A protease (also called a peptidase, proteinase, or proteolytic enzyme) is an enzyme that catalyzes (increases reaction rate or "speeds up") proteolysis, breaking down proteins into smaller polypeptides or single amino acids, and spurring the formation of new protein products. They do this by cleaving the peptide … Visa mer Based on catalytic residue Proteases can be classified into seven broad groups: • Serine proteases - using a serine alcohol • Cysteine proteases - using a cysteine thiol Visa mer Proteases occur in all organisms, from prokaryotes to eukaryotes to virus.
