Density of peroxynitrite
WebGenerally, cholesterol is transported to peripheral tissues by low-density lipoprotein (LDL), and then transported to the liver by high-density lipoprotein (HDL) via its cholesterol reverse transport function, and finally discharged. Under oxidative stress condition, LDL is commonly oxidized to the form ox-LDL, which is ingested by macrophages ... WebJul 19, 2013 · The role of reactive nitrogen species, such as peroxynitrite, in atherogenesis and the protective effect of dietary phenolic compounds are not yet understood. In this study, we sought firstly to determine whether phenolic acids become nitrated by peroxynitrite and then whether phenolic acid nitration can prevent consumption of γ-tocopherol and ...
