Tocopherols are lipid-soluble compounds synthesized only by photosynthetic eukaryotes and oxygenic cyanobacteria. The pathway and enzymes for tocopherol synthesis are homologous in cyanobacteria and plants except for 2-methyl-6-phytyl-1,4-benzoquinone/2-methyl-6-solanyl-1,4-benzoquinone methyltransferase (MPBQ/MSBQ MT), which catalyzes a key methylation step in both tocopherol and plastoquinone...
Tocotrienol mixtures have been shown to exert anabolic actions on the skeletal system in animal studies, but it is unclear which tocotrienol isomer shows most prominent effects. This study aims investigate active isomers using hFOB 1.19 human osteoblasts cultured a bovine bone scaffold. The trabecular was sectioned, demineralised and freeze-dried form were scaffolds humidified condition at 37 °...
INTRODUCTION: Strenuous exercise in sedentary individuals increases the acute risk of atherothrombotic events and depletes endogenous antioxidants. Supplementation with the antioxidant tocopherol ameliorates the risk; however it is unclear whether α-tocopherol, γ-tocopherol or a combination of both is more efficacious. We therefore measured the effects of γ-,αand mixed tocopherol supplementatio...
Bioefficiencies of alpha-, gamma- and delta-tocopherol in comparison with all-rac-alpha-tocopherol were established in broiler chickens. For this, 1-d-old male broiler chickens received a diet deficient in vitamin E and supplemented with increasing doses of the corresponding tocopheryl acetates. After 2 and 3 weeks of feeding, the animals were killed to obtain blood and liver samples. The ex vi...
