Quinones

Acts as cyclic organic compounds containing two carbonyl groups in a six-membered ring, often involved in electron transfer and redox reactions.

Key Functions:

• Function as electron carriers in cellular respiration (e.g., ubiquinone/CoQ10).
• Serve as cofactors for various enzymes.
• Exhibit antioxidant properties.
• Involved in blood coagulation (e.g., Vitamin K).

Interacting Systems & Components:

• Electron Transport Chain (ubiquinone component)
• Enzymes (cofactors for)
• Isoprenoids (precursors for some quinones)
• Coagulation Factors (Vitamin K dependent)
