The latest short science news items from C&EN. The team proposes that SAM plays a dual role in the reaction. It donates a methyl group to the enzyme’s cobalamin cofactor and then serves as a base when ...

Radical chemistry occupies a fascinating niche at the intersection of reactive intermediates and advanced materials science, where the interplay of unpaired electrons underpins unconventional bonding ...

Free radicals have a terrible reputation. These reactive and unstable molecules have been associated with cancer, aging, and degenerative diseases such as Alzheimer's. Yet the body constantly produces ...

Free radicals are unstable molecules that can damage DNA, leading to diseases like cancer. Antioxidants from foods can neutralize free radicals and reduce their harmful effects. Oxidative stress ...

One of the central challenges for synthetic chemists is to impose control over free radicals. Highly reactive molecules with an unpaired electron, free radicals may be familiar to you; these are the ...

This molecule maintains a stable free-radical structure while being highly responsive to external stimuli, making it a versatile functional material. By adding a small amount of this organic molecule ...
