Dietary Induced Changes in Volatile Fatty Acid Formation from α-Cellulose-C14 and Hemicellulose-C14

Metabolism of pyruvic acid-2-C14 and hydroxypyruvic acid-2-C14 in algae.

The metabolism of pyruvic acid in the light and dark by Scenedesmus has been examined with two aims: to study the relationship of its metabolism to that of the intermediates of C1402 fixation and to compare its metabolic fate with that of hydroxypyruvate. The metabolism of hydroxypyruvic acid was compared with that of C1402 fixation in order to ascertain whether it might be a photosynthetic int...

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.

The biosynthesis of glucuronic acid from 1-C14-glucose.

Although many classes of substances found in the animal organism have been suggested as possible biological precursors of glucuronic acid (l), recent research has narrowed the number of these possibilities to two, namely hexoses (2,3) and trioses (4, 5). Various experimental techniques, including isotopic tracers, have been used in the effort to choose between these alternatives, but invariably...
