Pronunciation: [pˈɛɹəksˌɪda͡ɪz] (IPA) 
The word "peroxidise" is spelled with a "d" instead of a "s" due to its phonetic pronunciation. The IPA phonetic transcription for this word is /pəˈrɒksɪdaɪz/. The "d" sound is represented by the symbol /d/ while the "s" sound is represented by the symbol /s/. In this case, the "z" sound at the end of the word is pronounced as /daɪz/ which led to the correct spelling being "peroxidise" and not "peroxidize" using the "s" sound.
Peroxidase is an enzyme that can be found in various living organisms such as plants, animals, and microorganisms. It is the catalyst responsible for the oxidation of a wide range of substances by transferring a peroxide group from a peroxide compound to another organic or inorganic molecule. The peroxidase enzyme uses hydrogen peroxide (H2O2) as a co-substrate and can act on a variety of substrates, including phenols, aromatic amines, and various organic and inorganic compounds.
Peroxidases play a crucial role in many biological processes, including defense mechanisms against pathogens, cell signaling, and the regulation of certain metabolic pathways. They are particularly important in the detoxification of harmful free radicals and reactive oxygen species, which can cause damage to cells and tissues if not neutralized.
In laboratory settings, peroxidases are frequently employed in various applications such as immunoassays, diagnostic tests, and molecular biology techniques. They are used as detection agents for the presence or measurement of specific substances due to their ability to produce a colored or fluorescent product upon catalysis.
Overall, peroxidases are a class of enzymes that have a wide range of functions and are essential for many physiological and biochemical processes in living organisms.
To oxidise to the utmost degree.

The word "peroxidise" is derived from the word "peroxide". The term "peroxide" originates from the combination of two Latin roots: "per" meaning "through" or "thoroughly" and "oxide" referring to a compound that contains oxygen. Thus, "peroxide" literally means "through oxygen" or "thoroughly oxygenated". The suffix "-ise" is added to "peroxide" to form the verb "peroxidise", denoting the action of causing or undergoing oxidation with peroxide.
