 Determining net charge of a peptide at pH 4? I'm having trouble on figuring out how to determine the net charge of a peptide at pH of 4 and a pH of 11. Met-Pro-Lys-Glu-Asp-Leu-Cys-Val-Arg-Pro-Tyr-Ala-Ser-Arg I know in an acid, the terminals are protonated and in a base the terminals are deprotonated but how do I figure out everything in between? Peptide Sequence was cut off. Picking up from Pro: Pro-Tyr-Ala-Ser-Arg  |
