Next, the smaller proteins move into the small intestine, where pancreatic enzymes, trypsin and chymotrypsin, continue the breakdown of proteins into amino acids.

Northrop, however, managed to crystalize three digestive enzymes, pepsin, trypsin and chymotrypsin, and by painstaking experiments shown them to be pure proteins.

Proteinase inhibitors, affecting trypsin and chymotrypsin, have been found in seeds of A. cowleana and other species. but only at levels similar to those found in peas or beans-much lower than levels in soybeans or winged beans (Kortt, 1984).

Princeton began to work on the purification of the protein-splitting enzymes met with in the digestive apparatus and gradually succeeded in obtaining a number of them in crystallized form, e.g. the pepsin met with in the gastric juice and the trypsin and chymotrypsin in the pancreas.
-
In 1929 he isolated pepsin in pure crystalline form by techniques which were later used by himself and other workers to crystallize trypsin, chymotrypsin, carboxypeptidase, and pepsinogen.
-
The chymotrypsin crystals were twinned and therefore difficult to work with, and so Perutz continued with haemoglobin.
-
Bernal, Fankuchen, and Perutz [Nature, 141 (1938) 523] published a joint paper on X-ray diffraction from crystals of haemoglobin and chymotrypsin.

The most frequently used biological molecules included in the digestion models were digestive enzymes (pancreatin, pepsin, trypsin, chymotrypsin, peptidase, α-amylase, and lipase), bile salts, and mucin.
