oxidation

Unlike metals like iron, which rusts and corrodes dramatically, chromium remains stable after oxidation and subsequent burial.

Acetone is derived from decomposition of diacetic acid, and this in turn from beta-oxybutyric acid by oxidation.

Further study will reveal the fact that the difference is due to the lack of oxidation in the case of the glacial detritus.

Reduction then appears to involve a loss of positive charges by ions, oxidation a loss of negative charges.

It stimulates metabolic activity of tissue cells and secures more complete oxidation of energy-yielding elements.

For in the rarefied air at high altitudes there is insufficient oxygen to promote the normal oxidation of bodily tissue.
