Studies on Denatured Egg Albumin

The Reactions of Denatured Egg Albumin with Ferricyanide*

This paper describes the reactions between the reducing groups of denatured egg albumin and ferricyanide. Measurements have been made of the effects on the amount of ferricyanide reduced of varying the time, temperature, and pH of the reaction, and the concentration of ferricyanide; of adding the synthetic detergent, Duponol PC; and of treating the denatured protein before the ferricyanide reac...

The Optical Rotatory Power of Heat-denatured Egg Albumin

The Reactions of Denatured Egg Albumin with Ferricyanide

The following facts have been established experimentally. 1. In the presence of the synthetic detergent, Duponol PC, there is a definite reaction between dilute ferricyanide and denatured egg albumin. 0.001 mM of ferrocyanide is formed by the oxidation of 10 mg. of denatured egg albumin despite considerable variation in the time, temperature, and pH of the reaction and in the concentration of f...

Studies on Surface Denaturation of Egg Albumin*

Bull and Neurath (1) have reported a study of the kinetics of surface denaturation of egg albumin. The protein solutions were shaken in bottles for varying lengths of time, and the amount of denaturation determined. It was not possible, however, in their studies to establish the effect of the extent and rate of formation of surface. The present paper reports a study of surface denaturation occu...

The Reaction between Iodoacetic Acid and Denatured Egg Albumin * by Lawrence Rosner

The reaction between iodoacetic acid and sulfhydryl compounds has received much attention in recent years. Dickens (1) has shown that this reaction proceeds with the formation of HI and the substitution of a carboxymethyl group for the hydrogen of the thiol group. Smythe (2) has measured the rate of reaction of iodoacetic acid with various sulfhydryl compounds by estimation of the carbon dioxid...
