Four levels of protein structure. … WebAt a pH of about 7.2 (indicated by horizontal bar) 51 groups (mostly the glutamic and aspartic amino acids and some of the histidines) have lost their protons. At pH 12 most of the remaining ionizable groups (mostly lysine and arginine amino acids and some histidines) have lost their protons as well. [Pg.56] Web4 jul. 2024 · You can, of course, reverse the whole process by adding an acid to the ion we've just finished up with. That ion contains two basic groups - the -NH 2 group and the -COO - group. The -NH 2 group is the stronger base, and so picks up hydrogen ions first. That leads you back to the zwitterion again. theoretische lap
