 Title    Yields of 2-Deoxy-D-gluconic, D-Gluconic and Other Sugar Acids in Gamma-Irradiated Aqueous Solutions of D-Glucose  
 Abstract    H e r m a n n E s t e r b a u e r , J a c k S c h u b e r t , E d w a r d B. S a n d e r s , a n d Ch a r l e s C. S w e e l e y The yields of 2-deoxy-D-gluconic, D-gluconic and other sugar acids from 6 0 Co-gamma irradiated (dose rate = 4 Krads/min) D-glucose solutions are reported. The acids produced upon radiolyses were separated from glucose and neutral products by anion exchange, assayed by gas chromatography of the trim ethylsilyl derivatives, and definitive identification made by mass spectrometry. In He degassed, irradiated 0.055 M glucose G(2-deoxy-D-gluconic acid) = 0.62 and G(D-gluconic acid) = 0.20. The approximate G values for the other identified acids are: glyceric acid 0.03, 2-deoxy-tetronic acid 0.04, tetronic acid 0.03, 4-deoxypentonic acid 0.02, deoxyketogluconic acid 0.17. In N 20 saturated glucose solutions D-gluconic acid yields increased by a factor of ~ 1.9 while that of 2-deoxy-D-gluconic acid increased by a factor of only ~ 1.1.
