CATECHOL OXIDASE Meaning and
Definition
-
Catechol oxidase is an enzyme that belongs to the class of oxidoreductases. It is commonly found in various plants, fruits, and vegetables, as well as in some animals. This enzyme plays a fundamental role in the process of browning or discoloration of tissues upon exposure to oxygen.
The primary function of catechol oxidase is to catalyze the oxidation of catechols, which are chemical compounds containing a benzene ring with two hydroxyl groups attached to it. The enzyme achieves this by causing the removal of two hydrogen atoms from the catechol molecule, resulting in the production of ortho-quinones. These ortho-quinones are highly reactive compounds that can further undergo spontaneous reactions, leading to the formation of brown pigments known as melanins.
The presence of catechol oxidase in fruits and vegetables is primarily responsible for the browning process that occurs when they are cut or bruised. This enzymatic browning reaction negatively affects the quality and visual appeal of the affected produce. However, it should be noted that catechol oxidase also has some beneficial effects, such as providing defense against pathogens and pests.
In summary, catechol oxidase is an enzyme that promotes the oxidation of catechols, leading to the formation of brown pigments. Its presence in various biological systems contributes to the browning of tissues and affects the quality of fruits and vegetables.

Etymology of CATECHOL OXIDASE
The word "catechol oxidase" is composed of two parts: "catechol" and "oxidase".
- Catechol: The term "catechol" refers to a chemical compound called 1,2-dihydroxybenzene. It is derived from the Greek word "katekhēsis", meaning "to instruct". This compound is commonly found in various biological systems and serves as a substrate for the enzyme catechol oxidase.
- Oxidase: The term "oxidase" is derived from the word "oxidation", which comes from the Latin word "oxydare", meaning "to oxidize". "Oxidase" is a suffix used to name a specific class of enzymes involved in oxidation reactions.
Therefore, "catechol oxidase" refers to the enzyme that catalyzes the oxidation of catechol compounds.
