- Use a rough diagram to compare the structures of a proteina-helix and an antiparallel b-sheet. For simplicity, showonly the backbone atoms of the protein.Draw the structure of the amino acid arginine and indicate all ionizable groupsFind the sequence for protamine and determine how many arginines it has. Based on the predicted sequence for protamine, what is its overall charge expected to be at neutral pH?

(Use pKa values for side chains and terminal amino and carboxyl groups )(b) Estimate the pI for this peptide.
- Give typing answer with explanation and conclusion On paper draw a dipeptide, clearly showing the peptide bond joining the two amino acids together. If the two amino acids are valine and threonine, predict the overall charge of the dipeptide at pH 7. Do not forget to consider the amino (N-terminal) and carboxy (C-terminal) of the dipeptide, as well as the R groups. Select one: a. +2 b. -2 c. 0 d. -1 e. +1Construct a Venn diagram using the one-letter symbol of the amino acids. Provide a reason that indicates why the amino acids are groups according to the venn diagram.Suppose that cells are grown on amino acids that have all been labeled at the a carbons with ¹³ C . Identify the atoms in cytosine and guanine that will be labeled with ¹³ C .
