Summary Introduction
To review:
Definition of the following terminologies:
a. Ligand
b. Motor proteins
c. GTP (guanosine triphosphate)
d. Macromolecular crowding
e. Excluded volume
Introduction:
The working parts of a living organism consist of several supramolecular structures. These multi-subunit complexes work as molecular machines, like physical entities with moving parts that perform work as a result of force and distance. The molecular machine is similar to mechanical devices made by human beings.

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?
