[Tocopherol and vitamin A content in the lipids of whitefish]

The content of tocopherols and vitamin A was measured in lipids of light and dark muscles, brain, internal fatty tissues of the whitefish inhabiting the Ob basin. Depending on the localization, the content of tocopherols was found to vary from 11.1 to 35.6 mg/100 g while that of vitamin A from 1.96 to 8.10 mg/100 g. Tocopherols were shown to be concentrated in neutral lipids whereas vitamin A to be distributed more uniformly among neutral lipids and phospholipids. Tocopherols were stable on lipid storage at - 5 degrees C for 2 years, whereas vitamin A disintegrated 25% annually.
