Foods which contain edible oils will spoil once exposed to oxygen from the air due to oxidation reactions. This chemical change results in a bad flavour and smell from the food. If left exposed to ...

In this reaction, carbon is oxidised because it gains oxygen. At the same time, copper oxide is reduced because oxygen is removed from it.

The reactions that occur inside mitochondria can be divided into two broad classes: oxidative and reductive 2. In oxidative reactions, molecules lose electrons and are therefore oxidized.

This process transforms free electrons into a nonreactive form by proteins (enzymes). Antioxidants regulate oxidative reactions by inhibiting, delaying or hampering the oxidation of the substances4.

The cells in our bodies are like bustling cities, running on an iron-powered system that uses hydrogen peroxide (H₂O₂) not ...

A dilute solution of bromine is added to samples of heptane and cyclohexene. The bromination reactions and mechanisms are compared. UV light splits the bromine molecule into two reactive radicals, ...

Chemists unravel how bicarbonate can protect cells from oxidative stress in a study that challenges how cell damage has been studied for decades.
