11. Role of Trypsin
-Secreted in the zymogen form (Trypsinogen)and
activation is brought about by Enterokinase (secreted
by the intestinal mucosa ) and by Trypsin itself. Trypsin
is specific for cleaving peptide bonds contributed by
basic amino acids.
Required for activation of Chymotrypsin
 Required for conversion of pro-elastase to elastase
It is required for conversion of fibrinogen to fibrin
It has weak action on casein
