So let's begin on our side. So on this side, we have this terminal amino group, and it has a PKA value of eight. So 8.0 for this particular case. This group here, the PKA value is about 3.1. So we have, let's make this neater 8.03.1 and then we have to look at the side chain group. So for Glycine, this cannot lose an H atom, so it doesn't have a PK value.
