Abstract
One hundred mg of α, γ, or δ-tocopherol (as acetate) was given to carps on tocopherol-deficient diet and both total tocopherol contents and homologues distribution in each group of carps were determined. As compared with tocopherol contents in feces and left-over diets, the tocopherol found in carps at 24,48 or 96 hrs after intake of tocopherol was very low especially on dosage of δ-tocopherol. From the results of homologues distribution-patterns, α-tocopherol was always found in carps on administration of α, γ, or δ-tocopherol. α and γ-Tocopherols were found in them on administration of δ-tocopherol but no δ-tocopherol was found on administration of α- or γ-tocopherol. It was suggested that there occurs conversion of γ- or δ-tocopherol to α-tocopherol but no conversion of α-tocopherol to non-α-tocopherol. Increase of ubiquinone contents of carps in comparison with the control carps also suggested conversion of tocopherol to ubiquinone.
