Peptone
(gcide) | Peptone \Pep"tone\, 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]
Note: Pure peptones are of three kinds, amphopeptone,
antipeptone, and hemipeptone, and, unlike most
proteins, are not precipitated by saturating their
solutions with ammonium sulphate.

Amphopeptone
(gcide) | Amphopeptone \Am`pho*pep"tone\, n. [Gr. ? + E. peptone.]
(Physiol.)
A product of gastric digestion, a mixture of hemipeptone and
antipeptone.
[1913 Webster] |
Antipeptone
(gcide) | Antipeptone \An`ti*pep"tone\, 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] |
Dyspeptone
(gcide) | Dyspeptone \Dys*pep"tone\, 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] Dysphagia |
Hemipeptone
(gcide) | Hemipeptone \Hem`i*pep"tone\, n. [Hemi- + peptone.] (Physiol.
Chem.)
A product of the gastric and pancreatic digestion of
albuminous matter.
[1913 Webster]
Note: Unlike antipeptone it is convertible into leucin and
tyrosin, by the continued action of pancreatic juice.
See Peptone. It is also formed from hemialbumose and
albumin by the action of boiling dilute sulphuric acid.
[1913 Webster] |
Metapeptone
(gcide) | Metapeptone \Met`a*pep"tone\, n. [Pref. meta- + peptone.]
(Physiol. Chem.)
An intermediate product formed in the gastric digestion of
albuminous matter.
[1913 Webster] |
Parapeptone
(gcide) | Parapeptone \Par`a*pep"tone\, n. [Pref. para- + peptone.]
(Phisiol. Chem.)
A proteinaceous 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.
[1913 Webster] |
Propeptone
(gcide) | Propeptone \Pro*pep"tone\, n. [Pref. pro- + peptone.] (Physiol.
Chem.)
A product of gastric digestion intermediate between albumin
and peptone, identical with hemialbumose.
