Common NameLactucaxanthin
DescriptionLactucaxanthin, also known as tunaxanthin F, belongs to the class of organic compounds known as xanthophylls. These 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, lactucaxanthin is considered to be an isoprenoid lipid molecule. Animals are unable to synthesise carotenoids de novo, and rely upon the diet as a source of these compounds. Lactucaxanthin is a tunaxanthin that consists of ε,ε-carotene bearing hydroxy substituents at positions 3 and 3' (the 3S,3'S,6S,6'S-diastereomer) (ChEBI: 6357). Studies have shown an inverse relationship between the consumption of certain fruits and vegetables and the risk of epithelial cancer. Lactucaxanthin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, Lactucaxanthin has been detected, but not quantified in, several different foods, such as sorghums, tea leaf willows, pitanga, thistles, and spearmints. This could make lactucaxanthin a potential biomarker for the consumption of these foods. Carotenoids are isoprenoid molecules that are widespread in nature and are typically seen as pigments in fruits, flowers, birds and crustacea. Since carotenoids are among the micronutrients found in cancer preventive foods, detailed qualitative and quantitative determination of these compounds, particularly in fruits and vegetables and in human plasma, have recently become increasingly important. It is a carotenoid found in human serum and breast milk (PMID: 9164160 ). This attention has been mirrored by significant advances in cloning most of the carotenoid genes and in the genetic manipulation of crop plants with the intention of increasing levels in the diet. Lactucaxanthin is found in Amanses modestus, Coryphaena hippurus , Ctenopharyngodon idella, Cyprinus carpio , Gymnogobius isaza, Oreochromis niloticus , Oxyjulis californica, Sebastes flavidus , Seriola quinqueradiata , Siniperca scherzeri and Thunnus thynnus . Lactucaxanthin was first documented in 2009 (PMID: 19392686). Over recent years there has been considerable interest in dietary carotenoids with respect to their potential in alleviating age-related diseases in humans.
