Young rats (100 g) were fed either a myo-inositol-deficient or supplemented (control) diet for up to 14 days following a 12 h fast. At various times during this period animals were killed, livers were removed, and a microsomal fraction was prepared and assayed for CDPdiacylglycerol inositol transferase activity and for phosphatidylinositol-inositol exchange activity. Within 2 days after beginning the regimen, rats consuming the deficient diet had a 40% lower activity of the transferase than rats consuming the control diet. This difference was maintained throughout the feeding period and developed simultaneously with the accumulation of triacylglycerol in the deficient livers. In contrast, the specific activity of the exchange enzyme was unchanged by feeding the deficient diet.
