Hydroxyproline
From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history
Hydroxyproline is an amino acid and a major component of collagen. The formation of hydroxyproline is catalyzed via the enzyme procollagen-proline dioxygenase via a reaction that requires vitamin C.
Elevated plasma hydroxyproline is associated with increased risk of connective tissue injuries[1] and metabolic bone diseases.[2] Elevated levels of hydroxyproline, a marker of collagen breakdown, was found by Wenzhong Xiaoin the Severely Ill Patient Study.[3] Robert Naviaux’s work has suggested it as a possible biomarker for female ME/CFS patients.[4]
