Includes salivary diastase (ptyalin), pancreatic diastase (amylopsin), and malt diastase (Examples of amylolytic enzymes/carbohydrases)
Diastase/Amylase
Also known as salivary diastase (Examples of diastase/amylase)
Ptyalin
Also known as pancreatic diastase (Examples of diastase/amylase)
Amylopsin
Found in yeast and intestinal juice; converts sucrose to glucose and fructose (Examples of amylolytic enzymes/carbohydrases)
Invertase/Sucrase
Found in yeast and intestinal juice; converts maltose to glucose (Examples of amylolytic enzymes/carbohydrases)
Maltase
A fermenting enzyme; converts monosaccharides to alcohol and water (Examples of amylolytic enzymes/carbohydrases)
Zymase
Found in almonds; converts amygdalin to glucose (Examples of amylolytic enzymes/carbohydrases)
Emulsin
Found in white and black mustard (Examples of amylolytic enzymes/carbohydrases)
Myrosin
Found in pancreatic juice; converts fats to glycerol and fatty acids (Examples of esterases)
Lipase
Converts pectin to pectic acid and methyl alcohol (Examples of esterases)
Pectase
Responsible for digesting dietary fat (Examples of esterases)
Steapsin
Found in soybeans; converts urea to ammonia (Examples of esterases)
Urease
Found in gastric juice (pH=1.8); converts proteins to proteases and peptones (Examples of proteolytic enzymes)
Pepsin
More active than pepsin; works best in alkaline medium (Examples of proteolytic enzymes)
Trypsin
Found in intestinal juices; converts proteases and peptones into amino acids (Examples of proteolytic enzymes)
Erepsin
