Reaction of sodium aminohippurate with Folin's reagent.
ITIS WELL RECOGNIZED that the Folin phenol method (1) for the determination of protein is not specific. This method was in fact originally standardized with protein or tyrosine, and the Folin phenol reagent was shown to react with numerous mono-, di-, and trihydroxyphenols in addition to other substances (s). Although most of these substances are not present in sufficient amounts to interfere w...
متن کاملThe reaction of Koshland's protein reagent with tryptophan.
A valuable reagent for labelling the tryptophan residue in proteins has been described by Koshland and co-workers. 2, 3 The reagent, 2-hydroxy-5-nitrobenzyl bromide, HNBB,4 is both highly selective for the tryptophan residue under mild reaction conditions and introduces the environmentally sensitive E-nitrophenol chromophore (Amax (acidic) 320 rnp; Xmax (basic) 409 rnw) into the protein. It was...
متن کاملO-Anisidine Degradation by Fenton’s Reagent and Reaction Time Estimation
O-Anisidines (OAs) are extensively used as an intermediate for chemical reactions to produce various triphenylmethane and azo dyes, and also in manufacturing numerous pigments. They are found to be highly toxic and have carcinogenic properties, so it is imperative to treat OA solutions before disposal. In this study a promising approach to degrade OA solutions has been carried out using Fenton’...
