Hi Steve and all!
I am trying to work this problem out and I'm only partially putting all the information together but I'm still missing how to integrate part (d) and how to chose from the amino acids that don't contribute to the net charge of the oligopeptide.
Thanx in advanced!
You have isolated a new pentapeptide from a bacterium. A series of experiments reveals the following about your peptide:
a) The column elution profile from amino acid analysis of the pentapeptide yields five distinct peaks;
b) the pentapeptide strongly absorbs light at 280nm
c) the pentapeptide has a net charge of " -0.5 " at pH 10.5
d) bubbling oxygen into the petapeptide solution for an extended period of time result in decapenptides being formed.
What are the amino acids making up this oligopeptide? |
