Question

Draw the structure of serine. label all functional groups identify the stereogenic center and provide all possible configurations - use the appropriate nomenclature graph the concentrations of fully protonated, zwitterionic and fully deprotonated forms with respect to increasing pH show the titration curve of serine using 2 equivalents of OH. Make sure to label significant points and regions on the graph and indicate the relative concentrations of the various species. Calculate the isoelectric point and provide your reasoning for how you went about doing so.
