Description
Excerpt from The Biochemical Journal<br/><br/>The following note contains an account of certain experiments which were undertaken to test Paul Bert's hypothesis regarding the formation of lactose from glucose. Bert's first experiment was upon a guinea-pig, in whose mammary glands he searched for an intermediate substance out of which it would be possible to form lactose in an appreciable quantity, but he failed to discover any such substance. He next proceeded to remove the mammary glands from two goats which were subsequently allowed to become pregnant, and he tested the urine of these animals to see if he could find a reducing substance both during the period of pregnancy and for a short time after parturition. No such agent could be found in the urine of either of the goats during pregnancy, but in one of them for about nine days after the birth of the kid a substance which markedly reduced cupric sulphate was discovered in considerable quantity, while in the case of the other goat the effect produced was similar though less pronounced. Bert concluded that the reducing substance was glucose, but it does not appear that he employed any further test to differentiate it from other reducing agents. He supposed further that the glucose in the urine repre sented glucose which in normal animals would have been converted into lactose in the mammary glands.
