General description

Zeaxanthin is a carotenoid that belongs to the group of xanthophylls. A dihydroxy derivative of β-carotene, it is found in vegetables and fruits, besides the eyes and skin of humans. It is known to show anti-oxidant, anti-inflammatory, anti-apoptotic, and neuroprotective properties.

Application

The analytical standards can also be used as follows:

  • Optimization of an ultrasonic-assisted extraction procedure for obtaining zeaxanthin and lutein from corn gluten meal samples for their determination by high-performance liquid chromatography-UV-Visible detection
  • Simultaneous quantification of five carotenoids and two chlorophylls from soybean flour samples by reversed-phase high-performance liquid chromatographic (RP-HPLC) method combined with UV-Vis detector
  • Multi-residue analysis of carotenoids and apocarotenoids in intact human blood samples by supercritical fluid extraction and supercritical fluid chromatography-atmospheric pressure chemical ionization-triple quadrupole mass spectrometry detection (SFE-SFC-APCI/QqQ/MS)
  • High-performance liquid chromatography-diode array detector (HPLC-DAD) method-based determination of carotenoids in marigold flower and food supplement samples
  • Profiling of carotenoids and their isomers in different plant tissue samples by high-performance liquid chromatography (HPLC) using a C30 column and photodiode array (PDA) detection

Biochem/physiol Actions

Carotenoid pigment that contributes to the color of paprika. Zeaxanthin accumulates within the eye retina and is thought to decrease the incidence of macular degeneration.

The macular region of the primate retina is yellow in color due to the presence of the macular pigment, composed of two dietary xanthophylls, lutein and zeaxanthin, and another xanthophyll, meso-zeaxanthin. The latter is presumably formed from either lutein or

The molecular mechanisms that allow pathogenic bacteria to infect animals have been intensively studied. On the other hand, the molecular mechanisms by which bacteria acquire virulence functions are not fully understood. In the present study, we experimentally evaluated the evolution
