• Since the purified porcine enzyme has very little activity towards hydrogen peroxide or organic hydroperoxides the protective effect is not likely to be exerted by its enzymatic activity. (joplink.net)
  • May constitute a glutathione peroxidase-like protective system against peroxide damage in sperm membrane lipids. (joplink.net)
  • Instead, may protect sperm from premature acrosome reaction in the epididymis by binding to lipid peroxides, which might otherwise interact with phospholipase A2 and induce the acrosome reaction. (joplink.net)
  • It conjugates to drugs to make them more soluble for excretion, is a cofactor for some enzymes, is involved in protein disulfide bond rearrangement and reduces peroxides. (lookformedical.com)
  • By virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus, these compounds exhibit varying degree of antioxidant activity, depending on the site and number of methyl groups and the type of ISOPRENOIDS. (lookformedical.com)
  • It exhibits antioxidant activity by virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus. (lookformedical.com)
  • [17] Exposure to ultraviolet (UV) radiation can cause direct photooxidation and decompose peroxides and carbonyl molecules. (wikipedia.org)
  • May constitute a glutathione peroxidase-like protective system against peroxide damage in sperm membrane lipids. (nih.gov)
  • Trace element iodine is an essential component of the thyroid hormones triiodothyronine (T3) and thyroxine (T4), which promote basal metabolism, lipid metabolism, and protein synthesis. (nature.com)
  • Hydrogen peroxide (600 microM) significantly increased the left ventricular end-diastolic pressure, decreased the left ventricular developed pressure (i.e., it produced mechanical dysfunction), and decreased tissue concentrations of adenosine triphosphate and creatine phosphate (i.e., metabolic damage).

  • These mechanical and metabolic alterations induced by hydrogen peroxide were significantly attenuated by propofol (25 microM or 50 microM), while the increase in malondialdehyde was completely suppressed by propofol. (asahq.org)
  • The current study demonstrates that in the isolated heart, propofol attenuates both mechanical and metabolic changes induced by exogenously applied hydrogen peroxide. (asahq.org)
