peroxidation

This term is a specialized technical word used almost exclusively in biochemistry and organic chemistry. It describes a specific oxidative degradation process, most commonly associated with lipids (lipid peroxidation), which is a key mechanism in cellular aging and the development of various diseases.

Because it refers to a specific chemical process or reaction, it is treated as an uncountable noun. It is not used in casual conversation or general contexts, appearing instead in scientific journals, medical reports, and textbooks to describe the formation of peroxides.
