Cat. No.: HY-N9625
CAS No.: 126-29-4
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 .

9-cis-Epoxycarotenoid dioxygenase (EC 1.13.11.51) is an oxidoreductase that can catalyze multiple reactions, including reaction 1: convert a 9-cis-epoxycarotenoid and O2 into a 12'-apo-carotenal and 2-cis,4-trans-xanthoxin; reaction 2: convert 9-cis-violaxanthin and O2 into (3S,5R,6S)-5,6-epoxy-3-hydroxy-5,6-dihydro- 12'-apo-beta-caroten-12'-al and 2-cis,4-trans-xanthoxin; reaction 3: convert 9'-cis-neoxanthin and O2 into (3S,5R,6R)-3,5-dihydroxy-6,7-didehydro-5,6-dihydro-12'-apo-beta-caroten-12'-al and 2-cis,4-trans-xanthoxin.
