Origin & Effect

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 digestion)

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; limits the growth of bacteria that cause intestinal infections and diarrhoea and encourages the growth of beneficial 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 nitrogeous bases

DE 14

Salivary Amylase (Ptyalin)

human

mouth

polysaccharides into  maltose (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)
