4) Proteolytic enzymes
1. Proteolytic enzymes hydrolyze the peptide linkage between amino
acids, yielding a mixture of peptides of different molecular size and
free amino acids
① The ability of enzymes to hydrolyze a protein substrate is highly
variable
② The selection of suitable enzymes to produce compounds with
defined physicochemical and nutritional characteristics is essential
2. Proteolytic enzymes are classified by their hydrolysing mechanism
: endopeptidases or exoproteases
① Endopeptidases hydrolyze the peptide bonds within protein
molecules at random
② Exoproteases systematically remove amino acids from either the
N-terminus or the C-terminus
