Drawing peptides at different ph

WebFor simple amino acids such as alanine, the pI is an average of the pK a 's of the carboxyl (2.34) and ammonium (9.69) groups. Thus, the pI for alanine is calculated to be: (2.34 + 9.69)/2 = 6.02, the experimentally determined … WebIf the theoretical and experimental values are different, it suggests that the assumed conformation is not correct. • Peptides, with different amino acid residues (and thus different side chains) also have characteristic titration curves and a characteristic isoelectric pH (pI) at which they do not move in an electric field. 33
