Myo - Inositol Synthesis in the Milk of Lactating Rats

Abstract

|
|
A high concentration of myo-Inositol in rat´s milk was observed (61-91㎎. of myo-Inositol per 100g of milk) by gas-liquid chromatographic method, using a 3% SE-52 column.
Feeding experiments showed that approxirnately 85% of myo-Inositol in mills was from dietary origins the rest was considered to be synthesized by 1L-myo-Inositol-l-phosphate lyase. Results suggested that the biosynthesis was not sufficiently high to permit the maintenance of its myo-Inositol level in milk. However, study using(^(14)C)-glucose injection into lactating female rats confirmed biosynthesis myo-Inositol from glucose in mammary gland. This biosynthesis reached a maximum within an hour after (^(14)C)-glucose injection intraperitoneally as lactose biosynthesis did.
Study using (³H)-myo-Inositol confirmed that most of the myo-Inositol in milk was transported from blood plasma myo-Inositol against a concentration gradient. About four hours after the beginning of the injection of (^(14)C)-glucose, the specific radioactivity myo-Irositol in milk was 8% of that of glucose in the blood. When (³H)-myo-Inositol was injected, the specific radioactivity of myo-Inositol in milk was about 26% of that of blood six hours after injection.
