Adipic acid has been incorporated into controlled-release formulation matrix tablets to obtain pH-independent release for both weakly basicand weakly acidic drugs.It has also been incorporated into the polymeric coating of hydrophilic monolithic systems to modulate the intragel pH, resulting in zero-ord...
Compared with neochlorogenic acid at pH 5, the positions of α-CD and β-CD were permuted at a more acidic pH, while at basic pH α-CD, M-β-CD and HP-β-CD gave the more stable inclusion complexes. The solubility of neochlorogenic acid in water was shown to improve in the presence...
Also, the pH alters the absorbance spectra and the corresponding changes in{E}_{g}are notable. The pH mainly influences the natural condition of these Cu-based oxide nanostructures and directly affects spectral changes according to the basic or acidic surface environment. As noted beforehand, the ...
However, in principle, acid and basic properties are independent of the nature of the solvent, and the concepts of acids and bases are in fact of such a general character that we must consider it a necessary requirement of these concepts in general to formulate a pattern independent of the ...

CO2 availability is a critical parameter for fermentation performance and extensive experimental work has been presented to understand its effect at various pH. Studies of the metabolism of A. succinogenes have shown that succinic acid production from glycerol is mainly defined by the glycerol uptake ...
Amino acids (AA) are quaternary compounds of carbon, hydrogen, oxygen and nitrogen and are the basic components of human proteins. They can be divided into natural (ie, endogenous synthesis) and essentialamino acids(meaning they can only be obtained from the diet).l-valine,l-leucine, andl-...
2. Adipic acid has a mild and long-lasting sour taste, and its Ph value changes less in a larger concentration range, making it a better Ph value regulator. It can be used for jelly powder and solid beverage powder, the maximum usage is 0.15g/kg and 0.01g/kg respectively. ...

As the pH values of the canine small intestine were reported to be neutral or slightly basic46, Eudragit S100 (dissolution pH of around 7) was selected for the capsule coatings. As shown in Supplementary Table 6, increasing concentrations of Eudragit S100, as well as the number of coating la...
