Lactucaxanthin
Lactucaxanthin is a tunaxanthin that consists of ε,ε-carotene bearing hydroxy substituents at positions 3 and 3 (the 3S,3S,6S,6S-diastereomer) (ChEBI: 6357). It is a carotenoid found in human serum and breast milk (PMID: 9164160). Carotenoids are isoprenoid molecules that are widespread in nature and are typically seen as pigments in fruits, flowers, birds and crustacea. Animals are unable to synthesise carotenoids de novo, and rely upon the diet as a source of these compounds. Over recent years there has been considerable interest in dietary carotenoids with respect to their potential in alleviating age-related diseases in humans. 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. Studies have shown an inverse relationship between the consumption of certain fruits and vegetables and the risk of epithelial cancer. 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. (PMID: 1416048, 15003396) Lactucaxanthin 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, lactucaxanthin is considered to be an isoprenoid lipid molecule. Lactucaxanthin is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Lactucaxanthin can be found in a number of food items such as pepper (c. baccatum), caraway, japanese persimmon, and lambsquarters, which makes lactucaxanthin a potential biomarker for the consumption of these food products. Lactucaxanthin can be found primarily in blood and breast milk. D020011 - Protective Agents > D000975 - Antioxidants > D002338 - Carotenoids
