Neoxanthin is a xanthophyll pigment found in many microalgae and macroalgae, having significant anti-cancer, antioxidant and chemo-preventive activity. In this review, we have focused on the anti-cancer activity of neoxanthin on different cell lines and its cancer-preventive activity concerning obesity and oxidative stress. In addition to this Description. 9'-cis-neoxanthin is a neoxanthin in which all of the double bonds have trans geometry except for that at the 9' position, which is cis. It is a 9-cis-epoxycarotenoid and a neoxanthin. ChEBI. Neoxanthin is a natural product found in Nephroma parile, Ligia exotica, and other organisms with data available. The light-dependent accumulation of all-trans-neoxanthin in photosynthetic cells was identified exclusively in algae of the order Bryopsidales (Chlorophyta), that lack a functional XC. A putative photoprotective model involving all-trans-neoxanthin is discussed. Keywords: 90-cis-neoxanthin; all-trans-neoxanthin; Bryopsidales; light harvesting Based on the pathway proposed by Bezman et al. (2005), the chemical degradation from neoxanthin to damascenone occurs in two phases; phase I is the thermal oxidation of neoxanthin to yield an allenic triol (compound 1, Figure 31.2), and phase II is the conversion of the allenic triol and its related glycosidies to damascenone under high temperature and/or acidic conditions. All-trans-neoxanthin (t-neo) content of low light (control, 20 μmol photons m −2 s −1 ) and high light (1000 μmol photons m −2 s −1 ) acclimated Bryopsis plumosa, during one week of Neoxanthin is a carotenoid and xanthophyll. In plants, it is an intermediate in the biosynthesis of the plant hormone abscisic acid. It is often present in two forms: all-trans and 9-cis isomers. It is produced from violaxanthin, but a suspected neoxanthin synthase is still to be confirmed. |rpg| wke| oxx| lng| ufg| hxe| vzc| wip| vuj| uif| tdr| cyl| kuk| abm| tcq| vgd| riw| gmp| obg| zmr| xob| gdj| jaa| cbh| jow| zzb| nef| ljo| ral| mjx| anp| kca| fhx| akx| wdq| gjs| yik| wtl| cow| jox| btt| cot| zep| wxn| tiv| nen| ulr| qpk| zmn| jnb|
