MONOAMINE OXIDASE Meaning and
Definition
-
Monoamine oxidase (MAO) is a type of enzyme that plays a crucial role in the breakdown and metabolism of various neurotransmitters, such as serotonin, norepinephrine, and dopamine. It is found throughout the body, particularly in the brain, liver, and platelets.
The main function of monoamine oxidase is to facilitate the degradation process of monoamine neurotransmitters by catalyzing the oxidation of their amino groups. By breaking down these neurotransmitters, MAO helps maintain a proper balance of these chemicals in the brain and body. Any imbalance in the levels of these neurotransmitters can lead to various mental health disorders, including depression, anxiety, and bipolar disorder.
There are two types of monoamine oxidase: MAO-A and MAO-B. MAO-A primarily metabolizes serotonin, norepinephrine, and dopamine, while MAO-B predominantly breaks down phenethylamine and benzylamine. Both enzymes are crucial in ensuring that excessive levels of these neurotransmitters are kept in check.
In addition to its role in neurotransmitter metabolism, monoamine oxidase also acts as a regulator of blood pressure. By breaking down tyramine, a substance present in certain foods, MAO helps prevent an excessive increase in blood pressure. However, certain medications can interact with monoamine oxidase inhibitors (MAOIs), resulting in the inhibition of the enzyme's activity and potentially leading to an increase in blood pressure, known as the "cheese effect."
Overall, monoamine oxidase is a vital enzyme involved in the metabolism of neurotransmitters and the regulation of various physiological processes in the body.

Etymology of MONOAMINE OXIDASE
The word "monoamine oxidase" is derived from the combination of multiple components:
1. Monoamine: The term "monoamine" comes from the prefix "mono-" meaning "one" and "amine", which refers to a class of organic compounds containing a nitrogen atom with a lone pair, including molecules like dopamine, serotonin, and norepinephrine.
2. Oxidase: It stems from the word "oxidation", which refers to a chemical reaction involving the loss of electrons. "Oxidase" is a suffix used to denote enzymes responsible for catalyzing oxidation reactions.
Hence, "monoamine oxidase" specifically describes an enzyme that catalyzes the oxidation of monoamine compounds.
