Roland Stocker (born 5 October 1956 in Switzerland) is a Swiss Australian biochemist who discovered the antioxidant activity of bilirubin.
[2] Stocker was awarded a Diplom [im] Naturwissenschaften und Mathematik (Dipl.
), or Diploma in/of Natural Science, from the ETH Zurich in 1981 and a Ph.D. from the Australian National University in 1985.
[3] Stocker has made significant contributions to the understanding of the molecular action of Alpha-Tocopherol (vitamin E) during the oxidation of lipoproteins,[4][5] the antioxidant activities of ubiquinol-10 in lipoproteins,[6] the contribution of oxidation of low-density lipoprotein to atherosclerosis,[7] the understanding of how antioxidants and heme oxygenase-1 protect against atherosclerosis,[8][9] the role of myeloperoxidase to atherosclerotic plaque destabilization,[10] and the contribution of tryptophan metabolism by indoleamine 2,3-dioxygenase in the regulation of vascular tone in inflammation.
Stocker's twin brother, Peter, was also an Olympic rower for Switzerland.
