Arginine is the immediate precursor of nitric oxide
Copper is a required co-factor for cytochrome oxidase, for cytosolic anti-oxidant superoxide dismutase, and for the optimal cross-linking of collagen
Iron is required for the hydroxylation of proline and lysine
Serum albumin level
Serum albumin level less than 2 g/dl causes prolonged inflammatory phase,
decreased fibroplasia, neovascularisation and cell synthesis and wound remodeling and hence decreased wound healing.
Collagen is the major protein component of connective tissue; it contains mainly glycine, proline, and hydroxyproline.
Collagen synthesis requires hydroxylation of lysine and proline, and co-factors such as ferrous
iron and vitamin C.
