The K_(a) and K_(b) values of alpha-amino acids are very low. Explain. |
| Answer» Solution :The `K_(a)and K_(b)` values of `alpha`-amino acids are very low because, in `alpha`-amino acids, the acidic group is `-overset(+)(N)H_(3)` instead of `-COOH` in carboxylic acids and basic group is `-COO^(-)` instead of `-NH_2` is group in ALIPHATIC amines. FRO example , the `K_(a) and K_(b)` values of glycine are `1.6xx10^(-10) and 2.5xx10^(-12)` respectively. | |
