n. (Physiol. Chem.) A product of gastric and pancreatic digestion, differing from hemipeptone in not being decomposed by the continued action of pancreatic juice. [ 1913 Webster ]
n. [ Pref. dys- + peptone. ] (Physiol. Chem.) An insoluble albuminous body formed from casein and other proteid substances by the action of gastric juice. Meissner. [ 1913 Webster ]

n. [ Gr. pepto`s cooked. ] (Physiol. Chem.) (a) The soluble polypeptides produced by hydrolysis of protein; specifically the soluble peptides into which food is transformed by the action of the gastric and pancreatic juices. Peptones are also formed from protein matter by the action of boiling water and boiling dilute acids. (b) Collectively, in a broader sense, all the products resulting from the solution of proteinaceous 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. [ 1913 Webster + PJC ]
☞ Pure peptones are of three kinds, amphopeptone, antipeptone, and hemipeptone, and, unlike most proteins, are not precipitated by saturating their solutions with ammonium sulphate. [ 1913 Webster ]
n. [ Pref. pro- + peptone. ] (Physiol. Chem.) A product of gastric digestion intermediate between albumin and peptone, identical with hemialbumose. [ 1913 Webster ]
