Histidine persists in its neutral form between the pH of 6.00 (equivalent to pK a 3 for the side chain pyrrole NH group, which corresponds to the equilibrium between the positive and neutral form) and pH 9.17 (equivalent to pK a 2 of the amino group which corresponds to the equilibrium between the negative and neutral forms)
Mitochondrial impairment serves as a key driver of ferroptosis by elevating reactive oxygen species and promoting the iron-mediated Fenton process, wherein ferrous ions facilitate the transformation of hydrogen peroxide into highly reactive hydroxyl radicals, thereby exacerbating oxidative damage and triggering ferroptotic cell death (121, 125, 126)
