Name of Enzyme Substrate Location Task Products
Salivary Amylase (likes pH level of around 6.2-7.4) Amylose in the mouth Saliva which is released from the salivary glands Aid in the hydrolysis of the starch amylose into the disaccharide maltose (glycocidic bond) Maltose, and Amylose
Pepsinogen No substrate, inactive form of pepsin Produced in the gastric glands and released into stomach as gastric juice Inactive form of pepsin which is used until released into the stomach so the enzyme does not eat away at the stomach, when Pepsinogen and hydrochloric acid are combined the active state, pepsin, is formed Pepsinogen + HCL = Pepsin
Pepsin Protein Activated in the stomach when pepsinogen and HCL react An enzyme that aids in the hydrolysis of protein (peptide links) Large peptides
Lipase Lipids Secreted from glands in the pancreas (pancreatic juice) to the duodenum An enzyme that aids in the hydrolysis of ester links in lipids (ester links) Glycerol and a variety of fatty acids (saturated and unsaturated)
Erepsin Large peptides Secreted from the glands in the pancreas (pancreatic juice) into the duodenum An enzyme that aids in the hydrolysis of short chain peptides (peptide links) Amino Acids
Trypsinogen (inactive protein digesting enzyme) No substrate, inactive form of Trypsin Secreted from the glands in the pancreas (pancreatic juice) into the duodenum Inactive form of Trypsin which aids in the hydrolysis of large peptides (peptide links) Trypsinogen + enterokinase = trypsin
Pancreatic Amylase (likes pH level of around 6.2-7.4) Amylose, maltose Secreted from the glands in the pancreas (pancreatic juice) into the duodenum, since stomach is so acidic (pH of 2-3) bi carbonate is released into the pancreatic juice to neutralize the pH level An enzyme which aids in the hydrolysis of amylose (glycocidic bond) Maltose, Alpha Glucose
Enterokinase Trypsinogen Secreted from intestinal glands into duodenum (intestinal juice) Enzyme which activates trypsin Trypsinogen + enterokinase = Trypsin
Trypsin Large Peptides Formed when enterokinase activates it from its inactive for of trypsinogen An enzyme which aids in the hydrolysis of large peptides (peptide links) Small peptides
Maltase Maltose Secreted from intestinal glands into duodenum (intestinal juice) An enzyme which aids in the hydrolysis of maltose into  monosaccharides Alpha glucose + Alpha glucose
Sucrase Sucrose Secreted from intestinal glands into duodenum (intestinal juice) An enzyme which aids in the hydrolysis of sucrose into monosaccharides Alpha glucose + Beta fructose
Lactase Lactose Secreted from intestinal glands into duodenum (intestinal juice) An enzyme which aids in the hydrolysis of lactose into monosaccharides Alpha glucose + Alpha galactose
