Fomaldehyde (Marquis [ii] and Prochazka reagent), furfural, 4-methoxybenzalde-hyde, 4-(dimethylamino)-cinnamaldehyde and 4-(dimethylamino)-benzaldehyde (Ehrlich s, Van Urk s, Morgan-Elson or EP reagents) react according to this scheme with... [Pg.39]

The Ehrlich reagent, developed originally for the colorimetric assay of pyrrole derivatives, was shown by Ehrlich to give a color with certain glycoproteins, with and without prior alkali treatment (3). The reagent consists of dimethylaminobenzaldehyde in strong hydrochloric acid. This assay later became the basis for the Morgan-Elson reaction for the deter-... [Pg.230]

The Morgan-Elson assay (see Alternate Protocol 2) requires less than 1 hr for the preparation of all the reagents, but a one hour period is required for the reaction of the 2,4-pentadione solution with the amino-sugar samples. In conclusion, without considering the incubation time in the preparation of the reagents, 2 to 4 hrs working time should be enough to determine a sample concentration with any of the procedures. [Pg.659]

The traditional method of assay of 2-acetamido sugars is the Morgan-Elson reaction. This involves treatment of the sugars in base, which produces furans, and reaction of these furans in situ with Ehrlich s reagent (p-dimethylamino-benzaldehyde in acid), which generates delocalised chromophores, as shown in Figure 7.8." ... [Pg.667]

If iV-acetylglucosamine is heated with dilute alkali and then treated with -dimethylaminobenzaldehyde in hydrochloric acid (Ehrlich s reagent), a reddish violet colour is obtained. The mechanism of this Morgan-Elson reaction, which was developed for quantitative estimation of iV-acetyl-... [Pg.106]
