Antialbumid :: Antialbumid (n.) A body formed from albumin by pancreatic and gastric digestion. It is convertible into antipeptone.
Peptone :: Peptone (n.) Collectively, in a broader sense, all the products resulting from the solution of albuminous matter in either gastric or pancreatic juice. In this case, however, intermediate products (albumose bodies), such as antialbumose, hemialbumose, etc., are mixed with the true peptones. Also termed albuminose..
Metapeptone :: Metapeptone (n.) An intermediate product formed in the gastric digestion of albuminous matter.
Albuminose :: Albuminose (n.) A diffusible substance formed from albumin by the action of natural or artificial gastric juice. See Peptone.
Tryptone :: Tryptone (n.) The peptone formed by pancreatic digestion; -- so called because it is formed through the agency of the ferment trypsin.
Galactin :: Galactin (n.) An amorphous, gelatinous substance containing nitrogen, found in milk and other animal fluids. It resembles peptone, and is variously regarded as a coagulating or emulsifying agent..
Trypsin :: Trypsin (n.) A proteolytic ferment, or enzyme, present in the pancreatic juice. Unlike the pepsin of the gastric juice, it acts in a neutral or alkaline fluid, and not only converts the albuminous matter of the food into soluble peptones, but also, in part, into leucin and tyrosin..
Hemipeptone :: Hemipeptone (n.) A product of the gastric and pancreatic digestion of albuminous matter.
Amphopeptone :: Amphopeptone (n.) A product of gastric digestion, a mixture of hemipeptone and antipeptone..
Peptonoid :: Peptonoid (n.) A substance related to peptone.
Peptotoxine :: Peptotoxine (n.) A toxic alkaloid found occasionally associated with the peptones formed from fibrin by pepsinhydrochloric acid.
Parapeptone :: Parapeptone (n.) An albuminous body formed in small quantity by the peptic digestion of proteids. It can be converted into peptone by pancreatic juice, but not by gastric juice..
Proteolytic :: Proteolytic (a.) Converting proteid or albuminous matter into soluble and diffusible products, as peptones..
Propeptone :: Propeptone (n.) A product of gastric digestion intermediate between albumin and peptone, identical with hemialbumose..
Hemialbumose :: Hemialbumose (n.) An albuminous substance formed in gastric digestion, and by the action of boiling dilute acids on albumin. It is readily convertible into hemipeptone. Called also hemialbumin..
Antipeptone :: Antipeptone (n.) A product of gastric and pancreatic digestion, differing from hemipeptone in not being decomposed by the continued action of pancreatic juice..
Semiglutin :: Semiglutin (n.) A peptonelike body, insoluble in alcohol, formed by boiling collagen or gelatin for a long time in water. Hemicollin, a like body, is also formed at the same time, and differs from semiglutin by being partly soluble in alcohol..
Hemiprotein :: Hemiprotein (n.) An insoluble, proteid substance, described by Schutzenberger, formed when albumin is heated for some time with dilute sulphuric acid. It is apparently identical with antialbumid and dyspeptone..
Dyspeptone :: Dyspeptone (n.) An insoluble albuminous body formed from casein and other proteid substances by the action of gastric juice.
Peptogen :: Peptogen (n.) A substance convertible into peptone.
