SMILES: C[C@@](O1)(C[C@H](CC2(C)C)O)[C@@]12/C=C/C(C)=C/C=C/C(C)=C/C=C/C=C(C)/C=C/C=C(C)/C=C/[C@]34[C@](O3)(C[C@H](CC4(C)C)O)C
Biological Activity: Violaxanthin is a naturally derived diepoxy xanthophyll carotenoid and light-harvesting accessory pigment with biological activities such as antioxidation and anti-inflammation. Violaxanthin transfers excitation energy to chlorophyll a under low-light conditions. Violaxanthin participates in the xanthophyll cycle and dissipates excess light energy in the form of heat, thereby protecting thylakoid membrane lipids from photo-oxidative damage. Violaxanthin exhibits activities including inhibition of lipid peroxidation, quenching of singlet oxygen, scavenging of DPPH free radicals, and scavenging of ABTS+ free radicals. Violaxanthin can be used in antioxidant-related research[1][2][3].
