Abstract: | Trichloracetic acid soluble fractions from the mouse brain, liver, muscle and blood were chromatographed in three solvent systems after a subcutaneous injection of 5-3H-uridine (boric acid -- ethanol -- water -- ammonium hydroxide; n-butanol -- acetic acid -- water; IM ammonium acetate -- 95% ethanol). The amount of uridine converted to uracil in the brain and blood highly prevailed over that phosphorylated to UMP. On the contrary, the amount of 3H-;uracil was small in the LIVER AND MUSCLe, the majority of 3H-uridine being converted to UMP. |
