The paper is a theoretical discussion of the relationship between chemical structure and vitamin E activity. Of 10 representatives of the chromans, other than the tocopherols, only 2: 2-diethylchroman is biologically active. The activity of the tocopherols depends greatly on the nature of the long...
WE have been particularly interested in the report in NATUREby Bowden and Snow regarding the photochemistry of the vitamins, in view of our investigations of the absorption spectra of various vitamin Bconcentrates, a preliminary report of which was presented at the meeting of the American Chemical ...
THE experiments of Heyroth and Loofbourow have established a close correlation between the physiological activity of concentrates of vitamin B(after eliminating inactive purines and pyrimidines, which absorb in the same spectral region), and the intensity of the absorption band at 2600 A. They ...
Fig 1. Chemical structure formula and three-dimensional structure of Vitamin E succinate Vitamin E Succinate takes vitamin E’s antioxidant action one step further, and may help bring vitamin E into and across cell membranes. Succinate feeds directly into the Krebs cycle, our major metabolic pathwa...
