Amino acid reference chart contains the twenty amino acids found in eukaryotes, grouped according to their side chains and charge. The pka for each group is the negative logarithm (base 10) of the equilibrium constant for its deprotonation. Learn amino+acid acid pka values with free interactive flashcards.
