pka Table - pKa is an acid dissociation constant used to describe the acidity of a particular molecule. Its value is directly related to the structure of the given compound.
The pKa of COOH, or a carboxylic acid group, is between 3 and 5. Carboxylic acids have a low pKa due to resonant structures, and it can be lowered more through the inductive effect. Is a high pKa acidic or basic? A large pKa value usually means that a molecule is basic. A solution...

pKa - The pKa value is the negative base -10 logarithm of the acid dissociation constant (Ka) of a solution. The quantitative behavior of acids and bases in solution can be understood only if their pKa values are known. To learn more about Calculation o
One of the strongest acids, H-I has a pKa of -10. Water has a pKa of 14. [Note 2] Alkanes have a pKa of about 50. [Note 3] 2. The Four Components Of An Acid-Base Reaction In an acid-base reaction, a bond is formed at H and a bond is broken at H. Every acid-base rea...
The cAMP-PKA-CREB pathway is frequently activated in colorectal cancer. Adenylate cyclase overexpression or PDE4B silencing may increase cAMP levels in colon cancer [167,168]. In addition, the fermentation ofdietary fiber can generate short-chain fatty acids, which activate free fatty acid receptor...
