  <name>3,6-Epoxide-5-hydroxy-5,6-dihydrozeaxanthin</name>
  <description>3,6-epoxide-5-hydroxy-5,6-dihydrozeaxanthin is a member of the class of compounds known as xanthophylls. Xanthophylls are carotenoids containing an oxygenated carotene backbone. Carotenes are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. Carotenes belonging form a subgroup of the carotenoids family. Xanthophylls arise by oxygenation of the carotene backbone. Thus, 3,6-epoxide-5-hydroxy-5,6-dihydrozeaxanthin is considered to be an isoprenoid lipid molecule. 3,6-epoxide-5-hydroxy-5,6-dihydrozeaxanthin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 3,6-epoxide-5-hydroxy-5,6-dihydrozeaxanthin can be found in a number of food items such as orange bell pepper, green bell pepper, pepper (c. annuum), and red bell pepper, which makes 3,6-epoxide-5-hydroxy-5,6-dihydrozeaxanthin a potential biomarker for the consumption of these food products. </description>
