Meaning and Definition
A substance, usually an enzyme, that originates from living organisms and accelerates (catalyzes) biochemical reactions.
Any biological agent (e.g., whole cells, ribozymes) used to speed up chemical transformations, often in industrial or laboratory processes, without being consumed in the reaction. Sometimes used metaphorically for a person or event that triggers a significant biological or social change.

FAQ
Frequently Asked Questions
Yes, all enzymes are biocatalysts. However, not all biocatalysts are single enzymes; they can also be whole cells or other biological entities.
In very technical writing, the back-formation 'to biocatalyze/biocatalyse' is occasionally used, but the noun form is far more common and preferred.
Biocatalysts typically operate under milder conditions (temperature, pressure), offer high specificity, and are often biodegradable, making processes more sustainable.
They are crucial in the pharmaceutical, food and beverage, biofuel, and fine chemicals industries for efficient and selective synthesis.
A substance, usually an enzyme, that originates from living organisms and accelerates (catalyzes) biochemical reactions.
Biocatalyst is usually formal, scientific, technical in register.
Biocatalyst: in British English it is pronounced /ˌbaɪ.əʊˈkæt.əl.ɪst/, and in American English it is pronounced /ˌbaɪ.oʊˈkæt̬.əl.ɪst/. Tap the audio buttons above to hear it.

Mnemonic
Break it down: BIO (life) + CATALYST (something that speeds up a reaction) = a living-thing-derived speed-booster for chemical processes.
Conceptual Metaphor
A TOOL/FACTORY WORKER (efficient, specialized, reusable agent that performs a specific task in a 'production line' of metabolism).
