Major enzymes in protein digestion Flashcards
1
Q
Pepsin
A
- found in the stomach
- begins protein hydrolysis after HCl has denatured proteins
- cleaves bonds between hydrophobic and preferably aromatic amino acids (phenylalanine, tryptophan, and tyrosine)

Q
Gastrin
A
found in the stomach
3
Q
Trypsinogen
- cleavage site of Trypsin
A
- pancreas
- peptide linkages involving the carboxyl groups of arginine and lysine
4
Q
Cymotrypsinogen
- cleavage site of Chymotrypsin
A
- pancreas
- linkages involving the carboxyl ends of phynylalanine, tyrosine, and tryptophan
