Research ArticleOpen accessEvery word in the titleInduced Production of α-Tocotrienol by Co-Suppression of Tocopherol Cyclase Gene in Vegetable CropsUmaiyal Munusamy, Siti Nor Akmar Abdullah, Maheran Abdul Aziz et al.This study involves the induced production of α-tocotrienol by the co-suppression of tocopherol cyclase gene. The Tocopherol/Tocotrienol Cyclase (TC) is a key enzyme involved in the biosynthesis of α-tocotrienol. The partial conserved cDNA of TC gene isolated from the oil palm (Elaeis guineensis) that shared greater than 75% sequence identity with TC sequences from other plant species was used to … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 7,706 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleThe Effect of Physical Refining on Palm Vitamin E (Tocopherol, Tocotrienol and Tocomonoenol)Chiew Wei Puah, Yuen May Choo, Ah Ngan Ma, Cheng Hock ChuahThis study reports the effect of physical refining on palm vitamin E including α- tocopherol, α-, γ and α-tocotrienols as well as α- tocomonoenol. A method using HPLC with fluorescence detector using normal phase silica column is described. An isocratic elution with n-hexane/THF/2-propanol (1000:60:4, by vol.) as mobile phase was used. The structure of the α- tocomonoenol was determined using … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 8,362 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsEffects of Vitamin E on Stress Resorption, Lipid Profile and Reproductive Performance of Sokoto Red GoatsKehinde Matthias OKUKPE, Ling Shing Wong, Geetha Subramaniam et al.Vitamin E (α-tocopherol) plays a critical role in animal nutrition as an antioxidant, contributing to anti-inflammatory responses, immune function, and gene expression regulation. This study aimed to determine the optimal dietary level of vitamin E to alleviate the effects of environmental stress in Sokoto Red Goats transported from their native dry savannah belt to the humid derived savanna belt of … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 20 Mar 2026 · 1,509 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsThe Vitamin A and E Forms Influence Differently the Plasma Vitamin Concentrations in Newly Received CalvesLorenzo Buenabad, Alberto Barreras, Alejandro Plascencia, Richard Avery ZinnTen Holstein steer calves (105±3 kg) were used to evaluate bioavailability of two Vitamin A or E forms, “natural” (EA1) or “synthetic” (EA2), based on plasma vitamin concentrations during a 3-d period post injection(subcutaneous). Plasma retinyl palmitate and plasma Vitamin A concentration (retinol equivalent of all forms) was greater 24 and 48 h (P<0.01) post injection of retinyl palmitate vs … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 2 · 31 May 2021 · 6,798 accessesView PDF Cite
