Levuglandinとは 意味・読み方・使い方

Levuglandins are reactive aldehydes formed by the spontaneous rearrangement of prostaglandin H (PGH). Enantiomerically pure levuglandin (LG) E₂ can also be formed through the cyclooxygenase (COX) pathway by a rearrangement of the prostaglandin (PG) endoperoxide PGH ₂. They are nonclassic eicosanoids. One species, levuglandin E₂, (LGE₂), forms neurotoxic adducts with amyloid beta. Levuglandins and isolevuglandins can damage proteins by covalent adduction, thereby interfering with their normal functions. These lipid-derived protein modifications may serve as dosimeters of oxidative injury. Elevated plasma levels of isoLG-protein epitopes are associated with atherosclerosis but are independent of total cholesterol, a classical risk factor.
