Concept introduction:
Many amino acids are linked together through amide bonds to form a biologically large molecule known to be proteins.
Amino acid had both amino functional group and carboxyl functional group in a molecule.
Amino functional group is

Histidine is an amino acid with three titratable groups: an -NH," group (pK, = 9.2), a -COOH group (pK, = 1.8), and an imidazole (amine- like) group (pK, = 6.0). The titration curve for histidine is shown below with four points highlighted. (a) Identify which point on the titration curve corresponds to the pK, for each of the titratable groups, and which point corresponds to the pl. Explain your choices.
