Free radicals: definition, cause, and role in cancer
Medically reviewed by Marla Anderson, MD Key Takeaways Free radicals are unstable molecules that can damage DNA, leading to ...
Biochar is widely recognized as a promising material for improving soil health, cleaning contaminated water, and storing ...
A new study suggests that unrepaired DNA damage can increase the speed of aging. Every day, our bodies face a bombardment of UV rays, ozone, cigarette smoke, industrial chemicals and other hazards.
Photochemical reactions begin by absorption of energy in the form of light, and involve formation of free radicals and transient excited states whose physical and chemical properties are very ...
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 ...
