Summary
Magnetic fields influence chemical reactions via the radical pair mechanism. Few biological reactions show this magnetic field sensitivity, but their relevance is discussed.
Area of Science:
- Biophysics
- Chemical Physics
- Biochemistry
Background:
- The radical pair (RP) mechanism is a known pathway for magnetic field effects in chemical reactions.
- However, documented cases of biological reactions utilizing RP intermediates and exhibiting magnetic field sensitivity are scarce in scientific literature.
Purpose of the Study:
- To review and discuss the current and potential future significance of magnetic field effects (MFEs) in biological systems.
- To highlight the limited but important examples of biologically relevant radical pair mechanisms.
Main Methods:
- Literature review and synthesis of existing research on magnetic field effects in chemical and biological systems.
- Analysis of the radical pair mechanism in the context of biological processes.
Main Results:
- Established understanding of MFEs on chemical reactions via the RP mechanism.
- Identified a scarcity of reported biological reactions demonstrating RP intermediates and magnetic field sensitivity.
Conclusions:
- Despite limited examples, magnetic field effects on biological reactions are a relevant area of study.
- Further research into RP mechanisms in biology could reveal novel applications and understanding.

01:11Radical Reactivity: Overview
Radicals, the highly reactive species, gain stability by undergoing three different reactions. The first reaction involves a radical-radical coupling, in which a radical combines with another radical, forming a spin‐paired molecule. The second reaction is between a radical and a spin‐paired molecule, generating a new radical and a new spin‐paired molecule. The third reaction is radical decomposition in a unimolecular reaction, forming a new radical and a spin‐paired molecule. These three...
01:03Radical Formation: Overview
A bond can be broken either by heterolytic bond cleavage to form ions or homolytic bond cleavage to yield radicals. A fishhook arrow is used to represent the motion of a single electron in homolytic bond cleavage. There are two main sources from which radicals can be formed:
Radicals from spin-paired molecules:
Radicals can be obtained from spin-paired molecules either by homolysis or electron transfer. While two radicals are formed in the former, an electron is added in the latter, also known...

01:10Radical Reactivity: Steric Effects
The presence of electron-donating, electron-withdrawing, or conjugating groups adjacent to a radical center, imparts electronic stabilization to the radicals. Examples of such electronically-stabilized radicals are triphenylmethyl, tetramethylpiperidine‐N‐oxide, and 2,2‐diphenyl‐1‐picrylhydrazyl. These radicals are remarkably stable and are known as persistent radicals. Some of the persistent radicals can even be isolated and purified.

00:47Radical Formation: Addition
Radicals can be formed by adding a radical to a spin-paired molecule. This is typically observed with unsaturated species, where the addition of a radical across the π bond leads to the production of a new radical by dissolving the π bond. For example, the addition of a Br radical to an alkene yields a carbon-centered radical.
Similar to charge conservation in chemical reactions, spin conservation is implicit for radical reactions. Accordingly, the product formed must possess an unpaired...

01:33Radical Reactivity: Intramolecular vs Intermolecular
Radical reactions can occur either intermolecularly or intramolecularly. In an intermolecular radical reaction, a nucleophilic radical adds to an electrophilic alkene or vice versa. In such reactions, the radical and generally the alkene, which is also called the radical trap, are two different molecules. Additionally, for such intermolecular reactions to occur, the radical trap must be active, present in an excess concentration, and the radical starting material must have a weak carbon–halogen...
01:16Radical Reactivity: Nucleophilic Radicals
Radicals adjacent to electron-donating groups are called nucleophilic radicals. These radicals readily react with electrophilic alkenes. The SOMO–LUMO interactions are the driving force for the reaction, where the high-energy SOMO of the electron-rich, nucleophilic radicals interacts with the low-energy LUMO of the electron-deficient, electrophilic alkenes. Such SOMO–LUMO interactions are the basis of reactive radical traps, affecting the selectivity in radical reactions. For instance, consider...
