Production of beta-maltooligosaccharides of alpha- and delta-tocopherols by Klebsiella pneumoniae and cyclodextrin glucanotransferase as anti-allergic agents.

18 Aug 2009 The glycosylation of alpha- and delta-tocopherols using Klebsiella pneumoniae and cyclodextrin glucanotransferase (CGTase) was investigated. K. pneumoniae converted alpha- and delta-tocopherols into the corresponding beta-glucosides in 10 and 8% ... Read more...

Microbiological production of tocopherols: current state and prospects.

5 Jul 2009 Tocopherols are antioxidants that prevent various diseases caused by oxidative stress. Tocochromanols comprise four isoforms of tocopherols and four isoforms of tocotrienols but alpha-tocopherol is the most abundant and active isoform in human and ... Read more...

Feasibility for improving phytonutrient content in vegetable crops using conventional breeding strategies: case study with carotenoids and tocopherols in sweet corn and broccoli.

8 Jun 2009 Among vegetables, sweet corn ( Zea mays L.) and broccoli ( Brassica oleracea L. ssp. italica) are important sources of dietary carotenoids and tocopherols. Because medical evidence suggests that carotenoid and tocopherol health-promoting activity ... Read more...

Technical information about 'Tocopherols'

Definition: A collective name for a group of closely related lipids that contain substitutions on the 2H-1-benzopyran-6-ol nucleus and a long hydrocarbon chain of isoprenoid units. They are antioxidants by virtue of the phenolic hydrogen. Tocopherols react with the most reactive form of oxygen and protect unsaturated fatty acids from oxidation.
