biochemistry please show your work 2. A mutant form of polypeptide hormone angiotensin II has the amino acid composition: Ile, Arg, Met, Leu, Phe, Asp, Tyr, and Val. The following observations are made: 1) Treatment with trypsin yields a dipeptide containing Asp and Arg, and a hexapeptide with all the rest. 2) Cyanogen bromide yields a dipeptide containing Phe and Leu and a hexapeptide containing all the rest. 3) Chymotrypsin cleaves the hormone into two tetrapeptides of composition: Val, Tyr,...
Calculate the net charge on the following peptide that contains an intramolecular disufide bond at pH 12. Assume that the peptide and disulfide bonds are stable at this pH. This question does not require you to draw the structure of this peptide, only to calculate the appropriate charge. You must identify where each charge comes from; you can't just give a final net charge number. Show all your work to obtain any-credit. (8 pts) QUESOn Calculate the net charge on...
