Principal Role of EPR Method in Discovery, Identification and Study of Dinitrosyl Iron Complexes in Living Organisms (Review)

This review is directly related to the new field of biology and medicine—the biology and medicine of nitric oxide (NO)—the simplest molecule produced in all living organisms and serving as one of the universal regulators of various metabolic processes. Specifically, this review concerns dinitrosyl iron complexes (DNICs) with thiol-containing ligands, which arise in living organisms and function in them, according to our data, as a “working form” of NO.
