Methods of treatment using water-soluble tryptophan-containing peptides obtained by the hydrolysis of hens eggs lysozyme

The present invention relates to a process to produce a composition comprising water-soluble peptides and having a Trp/LNAA ratio of more than 0.15, which comprises hydrolyzing lysozyme, preferably hen eggs lysozyme, to prepare a hydrolysate having a DH of between 5 and 45.

Synthesis and separation of L-trytophan oligo-peptides assisted by phosphorus oxychloride

With the assistance of inorganic phosphorus, α-amino acids could self-assemble into a series of oligopeptides, so it could provide a new route to synthesize peptides. In this paper, the self-assembly reaction of L-trytophan mediated by phosphorus oxychloride was monitored by using ESI-MS. The proper condition of the self-assembly reaction of L-Try was reported. The reaction products were purified by RP-HPLC and the fragmentation pathway for L-Try oligo-peptides were analyzed by using ESI-MS/MS.
