The origin of the glucose found In the blood of animals may be traced to several sources. When a carbohydrate diet is ingested the complex carbohydrates of the diet are converted into monosaccharides or simple sugars. These sugars are generally glucose, fructose, and galactose. The last two sugars, however, are transformed in part into glucose, Fructose, when fed in large amounts, is rapidly changed Into glycogen. Galactose its not stored as readily, and if given in excessive doses is partly excreted in the urine. It is interesting to note, however, that the sugar which Is lost in this way is not altogether galactose, but some other sugars which appear to be isomeric with it. Deuel and chambers (1) express the view that both fructose and galactose may first be broken down into trloses and then synthesized into glucose. They have been able to show in phlorhizinzed dogs a quantitative conversion of fructose into glucose. The conversion of galactose to glucose is not quantitative, as shown by the fact that Deuel and Chambers were able to recover only about 88 percent of the theoretical amount in the urine of these animals. The carbohydrates of the diet do not constitute the only source of glucose, for glycerol resulting from fat digestion may be converted into glucose. Chambers and Deuel have recently shown a practically complete conversion of glycerol to glucose in a number of the phlorhlzinized dogs with which they have worked.
