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.
High plasma hydroxyproline[edit | edit source]
ME/CFS[edit | edit source]
Elevated levels of hydroxyproline, a marker of collagen breakdown, was found by Wenzhong Xiao in the ME/CFS Severely Ill, Big Data Study.Robert Naviaux’s work has suggested it as a possible biomarker for female ME/CFS patients.
