Tryptone is the product after digesting casein with trypsin. We know what proteins make up casein and we know how trypsin digests. So is there like a database of the amino acids and peptides that compose tryptone?

​

Peptone, on the other hand, is the digest and hydrolysis of any protein. So it sounds like it can be made from any protein source and through enzymatic or chemical hydrolysis, so the composition can be undefined.

​

Meanwhile tryptose is similar to peptone, except that the protein source is specifically casein. So while the protein source is known, how it is digested could be through any means, so the compositions can be undefined.
