1. The reaction between ferricyanide and egg albumin in solutions of urea, guanidine hydrochloride, and Duponol has been investigated. 2. In neutral medium ferricyanide oxidizes all the SH groups of egg albumin that give a color reaction with nitroprusside. In neutral medium ferricyanide appears to react only with the SH groups of egg albumin. The quantity of ferrocyanide formed can accordingly...

1. Cyanide inhibits the oxidation of the SH groups of cysteine and denatured egg albumin by the uric acid reagent. 2. At pH 4.8 cysteine is oxidized by the uric acid reagent and by ferricyanide in the presence but not in the absence of added copper sulfate. 3. In neutral solution, the uric acid reagent oxidizes the SH groups of denatured egg albumin in the presence of urea but not in the presen...

1. The same number of SH groups reduces ferricyanide in surface films of egg albumin as in albumin denatured by urea, guanidine hydrochloride, Duponol, or heat, provided the ferricyanide reacts with films while they still are at the surface and with the denatured proteins while the denaturing agent (urea, heat, etc.) is present. 2. The SH groups of a suspension of egg albumin made by clumping t...

1. Quantitative precipitin studies indicate that progressive photo-oxidation progressively destroys the antigenic function of egg albumin. 2. Quantitative precipitin reactions of antisera (anti-egg albumin rabbit serum and antipneumococcus Type I horse serum) demonstrate that progressive photo-oxidation causes progressive lowering of the potency of the sera. 3. Quantitative precipitin reactions...

In present investigation, the effect of egg albumin on the rate of dissolution of analgesic tablets has been studied. Three sets of binder containing egg albumin in different ratios were used to prepare laboratory scale formulations and their dissolution behavior was studied. The best result was achieved from formulation having all the three binders (egg albumin, gelatin and corn starch) in 1:1...

the purpose of this study was to investigate the relationship of maternal breeding values of the weight of day-old chick chicks in a commercial broiler line with egg traits including yolk fatty acids. maternal breeding values of 63 hens of known pedigree were estimated through an animal model, containing direct additive genetic effect, maternal additive genetic effect, maternal common environme...

The amount of phosphorus in rice, though large in comprison with that of calcium, is not enough for the normal growth of rats and calcification of their bone. Moreover, the greater part of phosphorus in rice is phytin form of low digestibility. The authors have investigated the effect of addition of egg albumin and vitamin D to the rice diet on the availability of phosphorus in rice by rats. Th...

It was shown by Loeb (1) that an approximate correspondence exists between the isoelectric points of gelatin or of egg albumin when in solution or adsorbed on the surfaces of microscopic particles. It remained for Abramson (2) to demonstrate a quantitative agreement between his own results for the electric mobility of serum albumin adsorbed on quartz surfaces and measured by the microscopic met...
