Please create a titration curve (with relevant chemical state structures) for the dipeptide Aspartic Acid and lysine. Designate buffering regions. Human stomach fluid is typically found to be pH ~2 while human blood is typically found to be pH ~7.4. What is the predominant form of this dipeptide in each of these environments?

(this is my 2nd time asking please draw a titration curve for visual learning) thank you
