Draw the amino acid below in its most protonated form, any intermediately protonated forms, and its least protonated form. Also draw a titration curve for this amino acid, with pH on the y-axis and equivalents on the x-axis going from acidic to basic (most protonated to least protonated) using the pKa values below. Match the protonated/deprotonated forms to the appropriate regions of the titration curve. Scan your drawing, and upload as a pdf, jpeg, or tiff file. H3C N O OH
