Relevance. Reliable criteria for determining the region of origin of fruit products attract the constant attention of researchers in various countries. A number of approaches aimed at solving this problem are already known, and some progress has been made in interpreting experimental data for fruits on the content of stable isotopes of hydrogen, carbon, oxygen, nitrogen, and sulfur. It is possible that information about the fractionation of stable isotopes of magnesium will allow us to obtain equally important and reliable information to achieve the same goals.Methods. A mass spectrometer with inductively coupled plasma, standard samples of stable isotopes of magnesium produced in Russia were used to perform the work. The total concentration of magnesium cations was determined by atomic absorption in the flame and on the capillary electrophoresis system.Results. During the research, the mass and percentage ratio of three stable isotopes (24Mg, 25Mg, 26Mg) in the studied samples of apples grown in different soil and climatic zones was established. The data obtained reflect the relative prevalence of isotopes of this element, expressed in the ratio of the least common isotope to the most common. The deviation of the isotopic composition of Mg prototypes from the conventional standard was determined, significant deviations were obtained for the magnetic isotope 25Mg and non-magnetic 26Mg. The initial data on the fractionation of stable isotopes of magnesium in raw materials growing in different regions were obtained, with the aim of possible subsequent use as indicators in biochemical and physiological studies. A combination of the obtained information on Mg isotopes is assumed, taking into account the content of isotopes of other metals, which will make it possible to specify the region of growth of raw materials with greater reliability.

“…Since then, the term 'magnetic isotope effect' was dubbed for such phenomena as they are controlled by electronnuclear hyperfine coupling in the paramagnetic species. Moreover, isotope effects have been observed for a great variety of chemical and biochemical reactions involving oxygen, silicon, sulfur, germanium, tin, mercury, magnesium, calcium, zinc and uranium [65, 367,368,[375][376][377][378][379][380][381]. In this review, we focus on isotope effects from a spin perspective, see table 7.…”

Hundreds of studies have found that weak magnetic fields can significantly influence various biological systems. However, the underlying mechanisms behind these phenomena remain elusive. Remarkably, the magnetic energies implicated in these effects are much smaller than thermal energies. Here, we review these observations, and we suggest an explanation based on the radical pair mechanism, which involves the quantum dynamics of the electron and nuclear spins of transient radical molecules. While the radical pair mechanism has been studied in detail in the context of avian magnetoreception, the studies reviewed here show that magnetosensitivity is widespread throughout biology. We review magnetic field effects on various physiological functions, discussing static, hypomagnetic and oscillating magnetic fields, as well as isotope effects. We then review the radical pair mechanism as a potential unifying model for the described magnetic field effects, and we discuss plausible candidate molecules for the radical pairs. We review recent studies proposing that the radical pair mechanism provides explanations for isotope effects in xenon anaesthesia and lithium treatment of hyperactivity, magnetic field effects on the circadian clock, and hypomagnetic field effects on neurogenesis and microtubule assembly. We conclude by discussing future lines of investigation in this exciting new area of quantum biology.

A large and growing body of research shows that weak magnetic fields can significantly influence various biological systems, including plants, animals, and humans. However, the underlying mechanisms behind these phenomena remain elusive. It is remarkable that the magnetic energies implicated in these effects are much smaller than thermal energies. Here we review these observations, of which there are now hundreds, and we suggest that a viable explanation is provided by the radical pair mechanism, which involves the quantum dynamics of the electron and nuclear spins of naturally occurring transient radical molecules. While the radical pair mechanism has been studied in detail in the context of avian magnetoreception, the studies reviewed here show that magnetosensitivity is widespread throughout biology. We review magnetic field effects on various physiological functions, organizing them based on the type of the applied magnetic fields, namely static, hypomagnetic, and oscillating magnetic fields, as well as isotope effects. We then review the radical pair mechanism as a potential unifying model for the described magnetic field effects, and we discuss plausible candidate molecules that might constitute the radical pairs. We review recent studies proposing that the quantum nature of the radical pairs provides promising explanations for xenon anesthesia, lithium effects on hyperactivity, magnetic field and lithium effects on the circadian clock, and hypomagnetic field effects on neurogenesis and microtubule assembly. We conclude by discussing future lines of investigation in this exciting new area of quantum biology related to weak magnetic field effects.
