The Amide Nitrogen of Blood.
Certain chemical changes are known to occur in muscle during, and immediately following, short periods of exercise. With respect to the alteration in the acid-base equilibrium under such conditions, some facts are definitely established. It has been shown by Barr and Himwich (1) that within a few minutes after exercise very considerable, amounts of plasma bicarbonate are neutralized by acid, an...
متن کاملThe effect of ovalbumin and mannose-conjugated ovalbumin on the prevention of Salmonella adherence to the intestinal epithelium of chickens
This investigation was designed to determine the effect of intact ovalbumin and mannose-conjugatedovalbumin on the prevention of Salmonella typhimurium adherence to the epithelium of small intestine ofchickens. Mannose-conjugated ovalbumin was produced by Maillard-type reaction between chickenovalbumin and D-mannose at 60°C. The results revealed that incubation up to 96 hrs caused the highestam...
متن کاملStrong Hydrogen Bonding to the Amide Nitrogen Atom in an "Amide Proton Sponge": Consequences for Structure and Reactivity
The carbonyl oxygen atom of the amide functional group is universally believed to be the thermodynamically preferred site of protonation in amides;[1] however, N protonation has been proposed to play a key role in biologically important reactions of peptides and proteins such as acid-catalyzed peptide hydrolysis[2] and cis ± trans isomerization about the CÿN bond.[3] Extensive research into the...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
The Determination of Ammonia and Amide Nitrogen in Tobacco by the Use of Permutit.*
The accurate determination of the preexisting ammonia or of the amide nitrogt.n of tobacco is rendered difficult by the volatility of nicotine which distils over more or less completely when the standard procedures for the estimation of these forms of nitrogen are employed. A number of attempts has been made to devise methods whereby corrections for the nicotine content of such distillates may ...
