WebIn this study we compare the electrocatalytic activity of hemin (Hm), myoglobin (Mb) and hemoglobin (Hb) embedded in surfactant films of didodecyldimethylammonium bromide (DDAB) cast on glassy carbon electrodes for the electroreduction of nitrite in phosphate buffer solution (pH=7.4). The electrocatalytic behavior was studied by cyclic voltammetry … WebA label-free, sensitive and reliable electrochemical sensor based on hemin/G-quadruplex (G4) DNAzyme was engineered to determine adenosine triphosphate (ATP) in fish. The nucleic acid sequence (DNA1) including the G4 sequence subunit and anti-ATP aptamer segment is anchored on Au electrodes.

Hemin-Functionalized Reduced … WebHemin, an oxidized form of heme, acts as potent oxidant to regulate glutathione (GSH) content in pro-erythroid K562 nucleated cells, via activation of the KEAP1/NRF2 defensive signaling pathway. Moreover, GSH, as an essential metabolite, is involved in the regulation of cell-redox homeostasis and proposed to scavenge cytotoxic free heme, which is …
WebThe heme pathway is comprised of 7 steps that occur in the mitochondria and the cytoplasm. 7 In the first step, the substrates succinyl CoA and glycine are used by δ-aminolevulinic acid synthase (ALAS) to synthesize δ-aminolevulinic acid (ALA).
