    • Abstract

       

      An enzyme catalysing the hydrolysis ofa-tocopheryl acetate was characterised in chicken liver. The enzyme was localised in the microsomes, had an optimum pH 8.6 and aKm value of 0.5 mM. The enzyme did not hydrolyse retinyl acetate, cholesteryl acetate and ethyl acetate, thus indicating a high degree of specificity.a-Tocopheryl acetate hydrolase required bile salts as a specific co-factor. The results suggested a role for this enzyme in the absorption of vitamin E.
