these were made for several different purposes , namely , sythesis of n-acetyl-o-tosyl-4-hydroxy-l-proline amide as a model for chemical reduction of peptide-bound hydroxyproline , synthesis of tripeptides with the sequence glycyl-4-hydroxy-l-hydroxy-l-prolyl-x , synthesis of the naturally occurring sequence , glycyl-3-hydroxy-l-prolyl-4-hydroxy-l-proline , and monomers for polymerization to yield the sequence -glycyl-prolyl-4-hydroxy-l-prolyl- .
