superoxide dismutase
Học thuậtThân thiện
Definition
Noun: * An antioxidant enzyme: Superoxide dismutase is an enzyme that catalyzes the conversion of the superoxide radical (a harmful reactive oxygen species) into hydrogen peroxide and ordinary molecular oxygen. This is a crucial biochemical defense mechanism against oxidative stress in living organisms.
Examples of Usage
- Noun:
- The activity of superoxide dismutase is vital for protecting cells from damage.
- Researchers are studying the role of superoxide dismutase in the aging process.
- A deficiency in superoxide dismutase can lead to increased oxidative stress.
Advanced Usage
- Abbreviation (SOD): The term is frequently abbreviated to SOD in scientific literature.
- The SOD1 gene encodes a form of copper-zinc superoxide dismutase.
- Referring to specific types: It is often specified by its metal cofactor.
- Manganese superoxide dismutase is found in mitochondria.
Variants and Related Words
- SOD (n.): The common acronym for superoxide dismutase.
- Antioxidant enzyme (n.): A broader category to which superoxide dismutase belongs.
- Catalase (n.): Another enzyme that works in tandem with superoxide dismutase by further breaking down the hydrogen peroxide it produces.
Synonyms
- Antioxidant enzyme (contextual synonym)
- Radical scavenger (functional description)
Related Phrases
