The total number of basic groups in the following form of lysine is.........

 

A single pair of electrons can be donated by $-{\mathrm{COO}}^{-}$and ${\mathrm{NH}}_2$groups. Therefore, these two teams can serve as Lewis bases. Thus, these two categories are fundamental.
Due of its ability to donate the ${\mathrm{H}}^{+}$ ion, $\mathrm{NH}{3}^{+}$ has an acidic character.
As a result, there are a total of two basic groups in the lysine form described above.
