Common Name(s): Heptadecadienyl furan,heptadecadienyl furan,marine lipid antioxidant,furan fatty acid free radical scavenger

CAS Number: N/a

DESCRIPTION

What It Does: Provides exceptional lipid-phase antioxidant protection from the furan ring's singlet oxygen quenching — protecting sc lipids and formulation fatty components from photooxidative degradation at concentrations far below vitamin e.

Why It's Used: Furan fatty acids represent a unique class of lipid antioxidants — the furan ring's electron-rich pi system provides singlet oxygen quenching rates exceeding alpha-tocopherol by orders of magnitude from the resonance-stabilised radical intermediate.

How It Works: Furanoid fatty acid furan ring reacts with ¹o₂ via [4+2] cycloaddition → furanone intermediate → ring-opening products eliminating the peroxide; rate constant >10⁸ m⁻¹s⁻¹ for ¹o₂ quenching (vs alpha-tocopherol: ~5×10⁷ m⁻¹s⁻¹). the c17 alkyl chain provides lipid-phase solubility for membrane integration.
