Flavoprotein

Definition

Flavoproteins are a group of proteins that contain a nucleic acid derivative of riboflavin, such as FAD or FMN, and play crucial roles in redox reactions. They are essential in the electron transport chain and various other metabolic pathways.

5 Must Know Facts For Your Next Test

1. Flavoproteins often act as enzymes in oxidation-reduction (redox) reactions.
2. They contain flavin adenine dinucleotide (FAD) or flavin mononucleotide (FMN).
3. Flavoproteins participate in the electron transport chain by transferring electrons.
4. These proteins can be found in both prokaryotic and eukaryotic cells.
5. Mutations or deficiencies in flavoproteins can lead to metabolic disorders.
