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 کاملEffects of d-α-tocopherol and dietary energy on growth and health of preruminant dairy calves.
To observe the effects of supplemental dietary d-α-tocopherol in relation to dietary energy on growth and immune status in dairy calves, 32 newborn Holstein bull calves were assigned to 1 of 4 treatments for 5 wk in a 2 × 2 factorial, randomized complete block, split-plot design. Calves received moderate growth (MG) or low growth (LG) all-milk dietary treatments, formulated to support daily gai...
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 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 کاملChimeric Antisense Oligonucleotide Conjugated to α-Tocopherol
We developed an efficient system for delivering short interfering RNA (siRNA) to the liver by using α-tocopherol conjugation. The α-tocopherol-conjugated siRNA was effective and safe for RNA interference-mediated gene silencing in vivo. In contrast, when the 13-mer LNA (locked nucleic acid)-DNA gapmer antisense oligonucleotide (ASO) was directly conjugated with α-tocopherol it showed markedly r...
