Question 5. Which of the following pairs of bonds within a peptide backbone show free rotation around both bonds? A) Ca-C and N-C B) C-O and N-C C) C-O and N-Ca D) N-C and Ca-C E) N-Ca and N-C Question 6. In the diagram below, the plane drawn behind the peptide bond indicates the: A) absence of rotation around the C-N bond because of its partial double-bond character. B) plane of rotation around the C-N bond. region of steric hindrance...
Please explain each part !! Thank you !! #3. Under experimental conditions, you purify a known, biologically important peptide from human tissue. To determine the overall sequence, you then digest the pure peptide with trypsin and chymotrypsin (each separately) and then use mass spectrometry to identify the following sequence fragments from the overall peptide (shown in order of relative length, not necessarily in the order in which they are assembled in the whole, natural peptide). Trypsin cleavage products: Chymotrypsin cleavage...
Which of the following statements is NOT correct? A. Glycoproteins can have the carbohydrates in either O-glycosidic bonds to Ser or Thr residues or in N-glycosidic bonds to Lys residues. B. Glycosylated proteins are generally either extracellular proteins or membrane proteins with the carbohydrate residues on the extracellular side of the membrane. C. Penicillin is a mechanism-based inhibitor of a transpeptidase required for bacterial cell wall synthesis. D. Proteoglycans are composed of core proteins with one or more attached glycosaminoglycans....
