The naturally occurring α-tocopherol stereoisomer RRR-α-tocopherol is predominant in the human infant brain.
α-Tocopherol is the principal source of vitamin E, an essential nutrient that plays a crucial role in maintaining healthy brain function. Infant formula is routinely supplemented with synthetic α-tocopherol, a racaemic mixture of eight stereoisomers with less bioactivity than the natural stereoisomer RRR-α-tocopherol. α-Tocopherol stereoisomer profiles have not been previously reported in the h...
متن کاملExpression of α-tocopherol-associated genes and α-tocopherol accumulation in Japanese Black (Wagyu) calves with and without α-tocopherol supplementation.
The aim of the study was to clarify 1) the distribution of 6 α-tocopherol (α-Toc)-associated gene expressions in 20 major tissues, including metabolic, reproductive, endocrine, immune, and digestive and absorptive tissues, in relation to α-Toc status and 2) the change in expression patterns of the genes induced when α-Toc was orally administered to Japanese Black (JB) calves. This study examine...
متن کاملSpectrofluorimetric Determination of α-Tocopherol in Capsules and Human Plasma
A simple, sensitive and rapid spectrofluorimetric method for determination of α-tocopherol in pharmaceutical capsule and human plasma was developed and validated. The native fluorescence of α-tocopherol was measured at 334 nm with excitation at 291 nm, after extraction of α-tocopherol from human plasma hexane:dichloromethane mixture. The calibration curves were linear (R≥0.9993) in the concentr...
متن کاملBiomass and RRR-α-tocopherol production in Stichococcus bacillaris strain siva2011 in a balloon bioreactor
BACKGROUND Green microalgae represent a renewable natural source of vitamin E. Its most bioactive form is the naturally occurring RRR-α-tocopherol which is biosynthesized in photosynthetic organisms as a single stereoisomer. It is noteworthy that the natural and synthetic α-tocopherols are different biomolecular entities. This article focuses on RRR-α-tocopherol production in Stichococcus bacil...
متن کاملThe α-Tocopherol Transfer Protein Is Essential for Vertebrate Embryogenesis
The hepatic α-tocopherol transfer protein (TTP) is required for optimal α-tocopherol bioavailability in humans; mutations in the human TTPA gene result in the heritable disorder ataxia with vitamin E deficiency (AVED, OMIM #277460). TTP is also expressed in mammalian uterine and placental cells and in the human embryonic yolk-sac, underscoring TTP's significance during fetal development. TTP an...
