proteolysis

[ proh-tee-ol-uh-sis ]

Phonetic (Standard)IPA

noun

, Biochemistry.

proteolysis

/ ˌprəʊtɪəˈlɪtɪk; ˌprəʊtɪˈɒlɪsɪs /

the hydrolysis of proteins into simpler compounds by the action of enzymes: occurs esp during digestion

1875–80; proteo- (combining form representing protein ) + -lysis

C19: from New Latin, from proteo- (from protein ) + -lysis

“Flavor,” Cocalis notes, “is much more dependent on proteolysis, or the breakdown of proteins,” than mere appearance.

Pepsin-proteolysis, therefore, is strictly the proteolysis produced by pepsin-acid.

In digestive proteolysis we have a branch of physiological study which of late years has made much progress.

These two experiments thus give striking proof that free acid is not absolutely essential for pepsin-proteolysis.

Hence, it might be assumed that these two bases would likewise be formed in trypsin-proteolysis.

One of our conceptions regarding pepsin-proteolysis is that acid is necessary for every step in the proteolytic process.
