Incorporation of Glucose-
14C,
in vitro, into the sugar components of the three carbohydrate fractions of colonic mucosa from liver tumor (3'-methyl-4-dimethyl-aminoazobenzene-induced liver tumor)-bearing rats was studied, comparing with that from normal younger rats.
The results showed that the rate of incorporation of glucose-
14C into the sugar components of polysaccharide-containing fraction (
PS) was small, but those of carbohydrate fraction eluted with 50% aqueous ethanol from the charcoal-absorbed substances (
Et) and of carbohydrate fraction eluted with aqueous ethanol-ammonia from the charcoal-absorbed substances (
Et-
Am) were fairly large. And glucose-
14C incorporated much more into these carbohydrate fractions from the tumor-bearing rats than those from normal animals.
