THE EFFECT OF ISOELECTRIC AMINO ACIDS ON THE pH+ OF A PHOSPHATE BUFFER SOLUTION

THE EFFECT OF ISOELECTRIC AMINO ACIDS ON THE pH + OF A PHOSPHATE BUFFER SOLUTION A CONTRIBUTION IN SUPPORT OF THE ((ZWlTTER ION" HYPOTHESIS BY HENRY BORSOOK AND DOUGLAS

In recent years the conception in biochemistry of the ionization of amphoterie electrolytes developed by Walker (1) which is still generally accepted, has been gradually losing ground. The tendency has been to replace it with the hypothesis of Bredig (2), Adams (3) and Bjerrum (4), commonly designated as the "Zwitter Ion" hypothesis. The difference between the two hypotheses is represented by t...

Catalytic Effects of Carbon Nanotubes on Complexation of Some Amino Acids via Cobalt Cation Catalyst

In this research, investigation of the adsorption isotherms and the effect of solution conditions such as pH and concentration of complexation of some amino acids with cobalt(II) nitrate six-hydrate upon multi-wall type carbon nanotube (CNT) were done. The adsorption capacity of complexation of amino acids onto the surface of carbon nanotube increased with the pH from acidic to alkaline. At pH ...

Effect of Amino Acids on Magnesium Ammonium Phosphate Hexahydrate (Struvite) Crystallization

Amino acid and fatty acid profiles of materials recovered from Prussian carp, Carassius gibelio (Bloch, 1782), using acidic and basic solubilization/ precipitation technique

Isoelectric solubilization /precipitation (ISP) process was used to isolate protein from muscles of Prussian carp, Carassius gibelio (Bloch, 1782). Fish protein and lipid were recovered from whole gutted Prussian carp using acidic and basic isoelectric solubilization/precipitation followed by assaying amino acid and fatty acid profile. Essential amino acids content in acidic and basic pH treatm...

Electrophoretic behavior of mammalian-type cytochromes c.

Anomalous boundaries resulting from the binding of a buffer constituent give the appearance of electrophoretic inhomogeneity to pure crystalline native monomeric cytochromes c from 10 species (man, horse, hog, guanaco, Pekin duck, pigeon, turkey, tuna, a moth (Samia cynfhia), and the screw worm fly). The electrophoretic patterns depend on the particular cytochrome c used and its concentration, ...
