faqs pka and acidity the molecular structures of acids and bases have a direct impact on ph and pka values. chemists can also use pka to determine acidity that isn’t dependent on the amount of acid present. a substance’s pka value indicates how many acidic ions it will produce in a ...
Explore the concepts of pKa and pH values and how they relate to acids and bases. Learn the trends in pKa value for functional groups, acids, and...

Neutral LogP values from liposomes tend to be very similar to those measured in octanol but the ion-pair LogP values differ. The "Surface Ion Pair" log P is found to be much higher in bases, zwitterions and amphophiles. The values for acids tend to be similar to the octanol values. ...
Oxidation of uracil (U) and thymine (5-Me-U) are believed to play a role in genetic instability because of the changes these oxidations cause in the ionization constants (pKa values), which in turn affects the base pairing and hence coding. However, interpretation of the experimental evidence...
