Amino acid glycine `(NH_(2)-CH_(2)-COOH)` exists as a zwitter ion in aq. Solution. The `K_(a)` and `K_(b)`  values of glycine are `1.6xx10^(-10)(Pk_(a)=9.8)`and `2.5xx10^(-12)(pk_(b)=11.6)` respectively. The `K_(a) and K_(b)` values are for zwitter ion of Amino acid with following strctures `[NH_(3)^(+)-CH_(2)-COO^(-)]`   What is the `K_(b)` for `-NH_(2)` group in glycine?
