The stаbility оf cоllаgen is cоrrelаted with hydroxyproline content, however it was not clear what property of the -OH moiety is responsible for this observation. To figure out the reasons behind this observation, scientists synthesized three peptides and assessed their stability. Specifically, they tested a peptide containing only proline and glycine (Pro-Pro-Gly)10; one containing proline, hydroxyproline (Hyp), and glycine (Pro-Hyp-Gly)10; and one containing a fluorinated analog of hydroxyproline (Flp), in which the F atom is substituting for the -OH moiety (Pro-Flp-Gly)10. Briefly explain why fluorine was a good choice to replace the -OH group in hydroxyproline for this experiment.
