Effect of Prolonged Consumption of Lactose or Hydrolyzed Lactose in Rats.--5. Intestinal Metabolism of Glucose and Galactose. The intestinal metabolism of galactose is different according to the form of ingestion. With a lactose diet (L), the galactose is abundant in intestinal contents (Tab. I), since neither the intestinal flora (Tab. II), nor the epithelial tissue (Tab. III) can easily metabolize the galactose. The glucose disappears more rapidly than the galactose (Tab. I). With a hydrolyzed lactose diet (LH), the intestinal contents of two hexoses are identical (Tab. I). In this case, the enzymic activity of epithelium metabolizes an amount of galactose 6 times as big as with the lactose diet (Tab. III).
