Textbook Question
Chapter 10, Problem 20P
The transport of aspirin (pKa = 3.5, structure shown here) form the digestive tract to the circulation occurs by nonmediated absorption into cells lining the stomach (where pH=0.8) and the small intestine (where pH=6.0). Do you expect absorption to be faster in the stomach or in the small intestine?

Two tetrapeptides were isolated from a possum's sweat glands. These peptides were sequenced using Edman degradation and the following 2 sequences were obtained:
Gly-Asp-Ala-Leu
Gly-Asp-Asp-Leu
Can you please help show the titration curve for both of these peptides and calculate the PI?
