Function
DE 1
Carboxypeptidase
Cow
Pancreas
Peptides into other peptides and amino acids (protein digestion).
DE 2
Chymotrypsin
Cow
Pancreas
Protein into peptides (protein digestion).
DE 3
Deoxyribonuclease
Cow
Pancreas
& small intestine
Converts deoxyribonucleic acid nucleotides(DNA) into pentoses and nitrogenous bases
DE 4
Enterokinase
Pig
Small intestine
Converts inactive trypsinogen into active trypsin in small intestine (protein dig)
DE 5
Galactosidase/
Lactase
Cow
Small intestine
Converts lactose into glucose and galactose.
DE 6
Lipase
Human
Small intestine
Converts fat into fatty acids and glycerol (fat digestion).
DE 7
Lysozyme
Chicken
Egg White
Mouth (saliva),
tears and sweat
Destroys bacteria and so helps prevent tooth decay; works to limit the growth of the bacteria that cause infections and diarrhoea, and encourage the growth of good bacteria.
DE 8
Maltase
Baker’s Yeast
Small intestine
Converts maltose into glucose
DE 9
Pepsinogen
Pig
Stomach
Converted by hydrochloric acid into pepsin (protein digestion).
DE 10
Pepsin
Pig
Stomach
Converts proteins into peptides (protein digestion).
DE 11
Peptidase
Pig
Small intestine
Peptides into amino acids (protein digestion)
DE 12
Rennin
Calf
Stomach
Milk protein into casein which allows pepsin to act on it.
DE 13
Ribonuclease
Cow
Pancreas
& small intestine
Converts ribonucleic acid (RNA) into pentoses and nitrogenous bases.
DE 14
Salivary Amylase
(Ptyalin)
Human
Mouth
Polysaccharides into maltose, which is a disaccharide (carbohydrate digestion).
DE 15
Sucrase
Bacteria
Small intestine
Sucrose into glucose and fructose.
DE 16
Trypsin
Pig
Pancreas
Protein into peptides;
activates procarboxypeptidase into carboxypeptidase (protein digestion).
