Oxidation

Cut apple slices turn brown due to oxidation.

Oxidation of fatty acids leads to a decrease in the use of glucose on the periphery.

Researchers from five North American universities have collaborated on a study that found the process in fully oxidizing the atmosphere didn’t happen suddenly, but instead took place in scattered bursts over an approximately 100-million-year period in what has become known as the Great Oxidation Event.

Green tea undergoes minimal oxidation, preserving its natural green color.

Oolong tea falls between green and black tea, with varying oxidation levels.

Firing or pan-frying tea leaves stops the oxidation process.

Full oxidation gives black tea its deep, robust flavor and dark amber color.

Black tea undergoes full oxidation, resulting in a rich, bold flavor and dark amber hue.

The oxidation and unique yellowing process of this tea type contribute to its distinct taste.

On the other hand, it can be observed that, with small exceptions, the S. pneumonia strains are the only Streptococci equipped with homospermidine biosynthesis and pyruvate oxidation pathways, which have been found to be involved in pathogenicity mechanisms [50 ] and in the counteraction of oxidative stress [51 ].
