"WebCharge of phenylalanine at pH 1? So on BP it says that both the carboxyl group and the amino group will be protonated because the pka of those groups is greater than the pH. I get that. But then they're saying the overall charge is +1. Wouldn't it be +2 because both groups are protonated? 😭😭😭 thank you so much!!! " - Phenylalanine charge at ph 10
