where are digestive enzymes produced within the digestive system
Digestive enzyme
Erepsin : converts peptones and polypeptides into amino acids . Maltase : converts maltose into glucose . Lactase : This is a significant enzyme that converts lactose into glucose and galactose . A majority of Middle - Eastern and Asian populations lack this enzyme . This enzyme also decreases with age . As such lactose intolerance is often a common abdominal complaint in the Middle - Eastern , Asian , and older populations , manifesting with bloating , abdominal pain , and osmotic diarrhea . Sucrase : converts sucrose into glucose and fructose . Other disaccharidases
