The cleavage of vitamin E galactoside in the rat tissue homogenates.
The stability of alpha-tocopheryl beta-galactoside in the presence of endogenous galactosidases in selected tissue homogenates (liver, kidney, ileum and brain) was estimated. High degree release of alpha-tocopherol from alpha-tocopheryl beta-galactoside in tissues of ileum, kidney and brain was observed (82%, 75% and 72%, increase above endogenous alpha-tocopherol, respectively). A possible enzymatic mechanism of the galactoside decomposition was proposed.
