Meaning and Definition
A protein containing a flavin nucleotide (FAD or FMN) as a prosthetic group, enabling it to act as an electron carrier in redox reactions.
A class of conjugated proteins crucial in biological oxidation-reduction processes, such as cellular respiration and photosynthesis. They often appear as enzymes (oxidases, dehydrogenases) and are characterized by their yellow colour.

FAQ
Frequently Asked Questions
No. Flavoproteins are proteins with a flavin cofactor, involved in redox reactions. Flavonoids are a large class of plant secondary metabolites (pigments), chemically unrelated to proteins.
The flavin nucleotide prosthetic group (FAD or FMN) absorbs blue light, giving the protein its characteristic yellow colour.
Yes, both singular ('a flavoprotein', 'the flavoprotein') and plural ('flavoproteins') forms are standard when referring to specific types or instances.
Virtually never in everyday conversation. It would only appear in advanced biology or biochemistry educational materials, scientific research news, or medical texts concerning metabolic diseases.
