Synthesis of D-Glucose-1-C14 and D-Mannose-1-C14
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 about 50 percent. Low yields in prior syntheses appear to have been due to several inefficient steps, and to the fact that extension of the carbon chai...
متن کاملConversion of glucose-1-C14 to pectin in the boysenberry.
Many authorities believe that pectins play a dominant r&e in the changes in texture of fruits during the ripening process, although the origin and fate of pectic substances in plant tissues are unknown ((1) p. 273). There is no evidence that in nature pectic substances are formed directly from galactose or galactan ((1) p. 277). To obtain some insight into the mechanism of pectin formation, glu...
متن کاملLabeling of glucose, ribose, and deoxyribose by 1- and 2-C14-glycine in regenerating rat liver.
The present study was intended to provide information on the carbon sources of deoxyribose in animal tissues. Some tracer studies (2-5) have indicated that ribose of certain nucleosides or nucleotides is converted to deoxyribose without rupture of the nucleosidic linkage. However, evidence from cell-free preparations of animal tissues (6, 7) as well as microorganisms (6) has suggested an origin...
متن کاملAscorbic acid synthesis from D-glucose-2-C14 in the liver of the intact rat.
Evidence that glucose1 is the ultimate g-carbon precursor of ascorbic acid in the rat was first obtained by Jackel, Mosbach, Burns, and King (1). They administered uniformly labeled glucose-C** to Chloretone-treated rats and recovered uniformly labeled ascorbic acid from the urine. Subsequently, Horowitz, Doerschuk, and King (2) and Burns and Mosbach (3) discovered that when glucose-l-C14 was a...
متن کاملThe metabolism of ascorbic acid-1-C14 and oxalic acid-C14 in the rat.
It is known that oxalic acid is a product of ascorbic acid metabolism in the guinea pig (1) and rat (2), and is formed in man from unidentified precursors (3). Oxalates are also of interest because of their occasional toxicity and unexplained deposition. Ascorbic, dehydroascorbic, and 2,3diketogulonic acids are known to give rise to oxalic and threonic acids in approximately quantitative yields...
