The Shroud of Turin: an Amino-carbonyl Reaction (maillard Reaction) May Explain the Image Formation
The Shroud of Turin is a large piece of linen that shows the faint image of a man on its surface: it has been claimed to be the shroud of Jesus. Here we report evidences that colour can be produced by reactions between reducing sugars, left on the cloth by the manufacturing procedure, and amines deriving from the decomposition of a corpse. Treatment of a cloth prepared according to the ancient ...

متن کاملFormation of flavor components by the reaction of amino acid and carbonyl compounds in mild conditions.
This work describe products of reactions between four alpha-dicarbonyl compounds (diacetyl, pentan-2,3-dione, glyoxal, and methylglyoxal) or two alpha-hydroxy ketones, (acetoine and acetol) and amino acids present in wines. The results shows the formation of odorous products or strong-smelling additives resulting from the Maillard and Strecker reaction in a primarily aqueous medium, at low temp...
متن کاملThe reaction between wool and phenyl isocyanate.
During some studies on the reactivity of the cystine linkages in wool, it was necessary to find methods for blocking the various polar side chains with minimum degradation of the fibre as a whole, and without introducing any coloration due to the reagent used. Various workers have found that the amino groups of proteins react readily with i8ocyanates in aqueous solution at pH 8 and 00 (Hopkins ...
متن کاملNature of the Reaction of Wool with Alkali
The course of the reaction of the cystine in wool with alkali has been reinvestigated. The earlier findings that one sulfur atom is split from each molecule of cystine are confirmed. Of the residual noncystine sulfur in the alka li-tregted wool, mbre than 25 percent has been accounted for as lanthionine. No signifi cant amounts of sulfhydryl groups are in the t reated wools. The results lead to...
