The iron and sulfur atoms in iron sulfide are joined ... if it is not already balanced In the example above (the reaction between copper and oxygen to make copper oxide), we get this in the ...

This challenging reaction, which requires the insertion of sulfur between two unactivated carbons, is catalyzed by biotin synthase, an enzyme that contains two iron-sulfur [Fe-S] clusters and SAM.

Copper and iron are ... is thanks to sulfur’s ability to form more than 30 allotropes, or different forms in the same physical state, and to the wide range of chemical reactions it participates ...

Details of the chemical reaction of oxygen with the [Fe-S] cluster reveal how this cofactor is used for oxygen sensing.

The study was published in Nature Synthesis. Led by Julian West, researchers developed a photocatalytic process that uses iron and sulfur catalysts activated by mild blue light to add chlorine atoms ...

created a photocatalytic method that adds chlorine atoms to organic molecules using iron and sulfur catalysts activated by mild blue light. The harsh chemicals and high temperatures needed for ...
