Webspecies of tryptophan. Photophysical data show that the oxidation of tryptophan occurs mainly by type I mechanism but the reaction progress for the formation of tryptophan stable products depend-ing upon oxygen. In this case the radical anion of NISiH, created by the reaction of NISiH triplet state with Trp, reacts with triplet oxy-WebAs a result, the pigment was identified as perlolyrine, which is a Maillard reaction product from tryptophan; however, its contribution to the total color of beer was very low. This pigment was present in various kinds of beer at the level of 3.2–14.0 µg/100 mL.

WebHi, indeed an imine is formed. But upon hydrolysis, it revert back to the starting material. But if you take the product, and instead of using 49, you would use 49', which is very similar but instead of an aldehyde, it would be an amine (and also it is not a salt), an imine would also form. And upon hydrolysis, give the product.
