Homework Answers
Pro-collagen is the precursor of collagen.
For formation of pro-collage structure, there should be alignment of 3- α helices.
This alignment requires di-sulfide linkages in C-terminal of the α helices pro-peptide chains.
The triple helical structure favors the formation of inter-strand bond and help in stabilization of the molecule
Answer: B
Add Answer to:
Disulfide bonds found in the C-terminal extension peptides in Procollagen ensure proper O A. hydroxylation by...

35. Insulin is a polypeptide hormone that contains two short polypeptide chains linked by two interstrand disulfide bonds. In order to sequence the polypeptide chains, the most logical order of events to perform would be: I: Reduce the peptides with mercaptoethanol. II: Sequence the peptides using Edman degradation. III: Separate the peptides by gel filtration. IV: Alkylate the peptides with iodoacetate a) I, IV, III, I 36. Which ONE of the following statements regarding chaperonin is INCORRECT?

Questions 7-15 The molecule is ethane
71 2 O ACTIVITY 1.2.1 Biological Macromolecules in 3-D 7. Orient the two molecules so that portions of the mo lecules that would normally form intermolecular bonds lie next to each other. In this activity, you will build molecular models of biologically important molecules using ball-and-spring molecular model 1) What intermolecular forces help to hold these mo- building kits and then you will view these and other molecules lecules together! of interest using computer-generated...
