Reactions of Xanthydrol
The method to be described for the determination of tryptophan is based on the reaction between xanthydrol and tryptophan in acid solution to form a highly colored, acid-stable product (1). In the presence of excess xanthydrol the formation of xanthydryltryptophan is directly related to the quantity of tryptophan in the solution. Although other indole derivatives likewise react with xanthydrol ...
متن کاملThe colorimetric microdetermination of urea nitrogen by the xanthydrol method.
Although many methods for the determination of urea nitrogen have been described, few have proved highly convenient for the accurate determination of small amounts of urea nitrogen without having to make use of special apparatus or techniques. Among the older methods, the Van Slyke gasometric method (1) is generally considered the most accurate, with an allowable error of 1 per cent. This metho...
متن کاملREACTIONS OF DIHYDROPYRIDINES WITH BENZYNE
Reactions of 1 ,Zdihydropyridines (la-c) and 1,4-dihydropyridines (2a-c) in the presence of benzyne (3) under thermal conditions, and in the case of (2c) under photochemical conditions, have been investigated. Benzyne acts as an oxidizing agent to convert dihydropyridine (la) and (2a) to the corresponding pyridine (4) or adds as a dienophile to (lb-c).
متن کاملFetal Reactions
By the use of ultrasound, chemical analysis and histologic techniques, the knowledge of embryo and fetal growth and developments is increasing steadily. It has been demonstrated that the fetus can respond to sound, bright light and touch. Accordingly, works on fetal responses to external stimuli during the third trimester may ultimately lead to improvements in the techniques of antepartum fe...
