Amide

Chemical Characteristics and Physiological Rôles of Glutamine.

“…An excellent review on this subject has been published by Chibnall (45). An earlier work by Taubóck and Winterstein (257) reviews not only the physiological róle of amides in plants but also methods of determination of amides.…”

3-(1,3-Benzodioxol-5-yl)-N-(2-methylpropyl)prop-2-enamide (fagaramide)

“…Many plants contain the alkaloid fagaramide (Taubock & Winterstein, 1933), (I), which has been shown to be a pharmaceutically active agent in many natural products (Adesina & Reisch, 1988). Although it is well known in terms of composition (Thoms & Thumen, 1912), its structure has not been reported.…”

Biochemical Methods for the Study of Nitrogen Metabolism in Plants

“…The hydrolysis of amide nitrogen occurs in the general hydrolysis, and may be taken as a first criterion of whether any hydrolyzing action takes place under a given set of conditions. Most methods of amide determination are based on the method of SACHSSE (18). VICKERY (22) showed that sulphuric acid is preferable to hydrochloric because of a reducing action the latter may have on nitrates in the presence of reducing substances.…”
