Free radical generation during delta-aminolevulinic acid autoxidation: induction by hemoglobin and connections with porphyrinpathies.
delta-Aminolevulinic acid (ALA), a heme precursor accumulated in acute intermittent porphyria and saturnism, undergoes autoxidation leading to ammonium ion and probably the correspondingExpand

Generation of active oxygen species during coupled autoxidation of oxyhemoglobin and delta-aminolevulinic acid.
The conversion of oxyhemoglobin to methemoglobin has been shown via spectrophotometric, circular dichroism and polarographic studies to be accelerated by delta-aminolevulinic acid, a majorExpand

Nitrated lipids decompose to nitric oxide and lipid radicals and cause vasorelaxation.
Nitric oxide-derived oxidants such as nitrogen dioxide and peroxynitrite have been receiving increasing attention as mediators of nitric oxide toxicity. Indeed, nitrated and nitrosated compounds haveExpand
