A convenient procedure is described for the radioassay of both carbon-14 and tritium in water-soluble, nonvolatile compounds by means of a windowless, gas-flow, proportional counter. The materials are counted in uniform films of sodium O-(carboxymeth

Heretofore, radiochemical yields of sugars position-labeled with carbon-14 have been only 5 to 10 percent. This paper reports an improved cyanohydrin synthesis, and the preparation of D-glucose-1-C and D-mannose-1-C from D-arabinose in yields of abou

d-Glucose-3-(14)C has been prepared by means of three, successive Kiliani syntheses. The process consists of (a) the addition of (14)C-labeled-cyanide to d-glyceraldehyde; (b) hydrolysis of the cyanohydrins and conversion of the resulting epimeric d-

In a new method for preparing aldoses labeled with tritium at carbon 1, the aldonic lactone is reduced with lithium borohydride-t in pyridine solution. The method is suitable for preparing aldoses-1-t having high specific activities. The crude produc
