| Abstract: | Radiolysis of some monosaccharides (fructose, glucose and ribose) in air-free condition was markedly enhanced by the addition of formate at concentrations above 20 mm, while it was inhibited at concentrations below 20 mm. The following compounds were detected in the irradiated sugar solutions containing excess formate (100mm): 1-Deoxy-d-arabinohexulose (1, G=4.4) and 1,3- dideoxy-d-erythrohexulose (2, G= 1.3) from fructose; 2-deoxy-d-ribose (3, G=2.3) and 2-deoxyribitol (4, G =0.6) from ribose; and 2-deoxy-d-glucose (5, G=0.5) and 2-deoxy-d-glucitol (6, G=0.4) from glucose. A mechanism for radiolytic formation of the products was proposed, based on interaction of  | |
