You can do this by calculating the charge at a number of different pH values, or use excel to do these calculations for you (5 pts) ii) Assume you want to purify this peptide for a mixture of other p ...
Mutation Reading--How the Gene for Sickle Cell Hemoglobin
... Each complete hemoglobin protein has more than 100 amino acids. Sickle cell hemoglobin and normal hemoglobin differ in only a single amino acid. This difference in a single amino acid results in the very different properties of sickle cell hemoglobin, compared to normal hemoglobin. If a person inhe ...
