Removal by the Isolated Rat Liver of Palmitate-1-C14 Bound to Albumin and of Palmitate-1-C14 and Cholesterol-4-C14 in Chylomicrons from Perfusion Fluid

Incorporation of Sulfate-s35 and Glucosamine-1-c14 into Heparin during Perfusion of Isolated Rat Liver.

• The addition of sulfate-S" to rat blood perfusing an isolated, surviving rat liver causes association of some of the isotope with several plasma protein fractions x in a pattern similar to that obtained when the isotope is injected in a living rat. Preparative starch block electrophoresis (pH 8.6) of aliquots of the perfusing plasma indicates that approximately 80$ of the bound radioactivity ...

The esterification of palmitate-1-C14 by homogenates of intestinal mucosa.

The 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...

Metabolism of Coprostanol-c14 and Cholestanol-4-c14 in Man.

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...
