- In N-linked glycoproteins, the sugar is usually attached to the protein by a bond to the N atom in a side-chain amide. Which amino acids can form such a bond?If a Cys residue in a protein was replaced with either Ser or Phe amino acid, which substitution would you expect to result in the greatest structural change and why?The β-sheet structure is the secondary structure of the protein which is a sideways folded structure of the polypeptide Draw the symbol of the β-sheet structure and Name 2 types of β-sheet and explain the difference
- Draw the structure of the following peptide as it would be at pH = 7. Does the molecule have a net charge at that pH? ExplainMet-Ser-Glu-Ala-Lys-Lys-GluWhat if the protein does not have a primary structure, what is its implication? Explain and give example.The R group in alanine is –CH3, whereas the R group in aspartic acid is -CH2CO2H. After consulting Figure 1-34, draw thecomplete Lewis structure for each of these amino acids.
