ESTIMATION OF THE FERMENTABLE CARBOHYDRATES IN RABBIT LIVER. ISOLATION OF A REDUCING DEXTRIN

C. B. Purves 1

1 The Department of Physiology, University of Aberdeen

(1) A carbohydrate easily fermented by yeast, free from glucose and glycogen, was isolated as a slightly impure, amorphous powder in 0·07 per cent. yield from rabbit liver. The solubilities and general properties of the carbohydrate were those of a mixture of dextrins containing free, copper-reducing groups. It gave no colour with iodine.

(2) The amorphous acetate of the above had a specific rotation of 127° in chloroform and a nitrogen content of 0·28 per cent. It contained no detectable amount of sulphur or phosphorus.

A Carnegie Teaching Fellowship enabled the author to carry out the work.
