Abstract
Purified prepns. of uridine-diphosphate-glucose (UDPG) were studied by paper chromatography and found to be contaminated with uridylic acid and a substance UDPX. The uridylic acid obtained by degradation of UDPG was identified as uridine-5[image]-phosphate. The alkaline degradation products of UDPG are uridine-5[image]-phosphate and a cyclic phosphate ester of glucose, probably esterified at positions 1 and 2 of the glucose. This ester decomposes with acid or alkali giving glucose-1-phosphate (25%) and glucose-2-phosphate (75%). The contaminating substance UDPX appears to have the same structure as UDPG except that it contains an unidentified component instead of glucose.
