peptone    
n. 胨



peptone
n 1: any of various water-soluble compounds that form by
hydrolysis in the digestion of proteins to amino acids

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.
[1913 Webster]
