Protein, under the same conditions, is changed to a peptone.
Thus, 7.5 grammes of peptone dissolved in water in such proportion as to make a five per cent.
Thus prepared, the peptone shows no signs of decomposition on keeping.
On the other hand, when peptone was introduced in larger quantity, viz., in a twenty per cent.
On now testing a portion of the clear filtrate for peptone by the biuret test, not a trace of a reaction could be obtained.
Its function is to convert the proteids into peptone, which is effected by its active principle, termed pepsin.
Heat in the steamer at 100° C. for twenty minutes to complete the solution of the peptone.
We have learned that in the digestive tract foods are converted into a soluble form of proteid known as peptone.
This is because the pancreatic ferment (trypsin) has digested the casein into "peptone," which does not curdle.
Steam in the steamer at 100° C. for twenty minutes to dissolve the peptone and glucose.

Any of various soluble compounds that do not coagulate, are obtained by acid or enzyme hydrolysis of natural protein, and are used as nutrients in culture media.
