1 maj 2021 · This review provides an overview of our current understanding of unicellular ferric reductases (both soluble and membrane-bound), with an emphasis on the important but underappreciated connection between ferric-reductase mediated Fe 3+ reduction and the transport of Fe 2+ via ferrous iron transporters.
14 wrz 2020 · The gastric secretions contain hydrochloric acid with a low pH, which promotes the reduction of ferric iron in the foods to ferrous iron. Gastric acid is one of the most important luminal factors being mandatory for an optimal nonheme iron absorption.
The two most common iron states are the divalent ferrous (Fe 2+) and the trivalent ferric (Fe 3+). Within the human body, iron is required as a cofactor for many haemoproteins and non-haem iron-containing proteins.
1 maj 2021 · Ferric iron (Fe3+) is reduced to ferrous iron (Fe2+) in order to enter the cell, and this can be achieved by ascorbate or membrane-bound reductases (Cain and Smith, 2021; Ganasen et al., 2018).
Ferric iron can be reduced to ferrous iron by strong reducing agents in the medium. Iron reducing agents of concern in cell culture include the superoxide radical and ascorbate. A widely studied cellular reductant and frequently used media component is ascorbate (Vitamin C).
A widely observed electronic transition discovered in iron compounds is the reduction from the ferric to the ferrous state. In a series of studies since 1967 such reduction has been observed in perhaps forty to fifty compounds including halides, cyanides, hydrates,...
Ferric reductases are broadly-distributed electron-transport proteins that are expressed by numerous infectious organisms and are connected to the virulence of unicellular pathogens. Despite this importance, ferric reductases remain poorly understood.
