Most common pkas
WebThere are 20 naturally occurring amino acids and all have common structural features – an amino group (-NH3+), a carboxylate (-COO-) group and a hydrogen-bonded to the same carbon atom. They differ from each other in their side-chain called the R group. Each amino acid has 4 different groups attached to α- carbon. These 4 groups are: Amino ...

WebCompare the pKa's. The pKa of the acid is near 5, and the pKa of the ammonium is near 9. The ammonium holds the proton more tightly than does the acid. The proton stays on the nitrogen. Amino acids are zwitterionic. A zwitterion is a compound that has no overall charge but that has charge separation within it. WebDoing the math, we find that the pK a of acetic acid is 4.8. The use of pK a values allows us to express the acidity of common compounds and functional groups on a numerical …
