Octadecenoic Acids in Humans: Plasma, Erythrocyte, and Platelet Phospholipids

The objective of this study was to follow the uptake and distribution of oleic and elaidic acids into human erythrocytes. platelets, and plasma phospholipids. The usc of dual and triple labeling methodology permitted a precise comparison of elaidic and oleic acid utilization. Elaidic acid (EI) was selectively concentrated in all th~ plasma phospholipids except for lysophosphatidylcholine. Three...

Fermentation in the Rumen of the Sheep Iv. the Nature and Origin of the Volatile Fatty Acids in the Rumen of the Sheep

Early workers in the field of ruminant physiology were aware of the presence of formic, acetic, propionic and butyric acids (Tappeiner, 1884), and of smaller amounts of higher members of the saturated fatty acid series (Mangold, 1934), in the rumen fluid. Accurate data were not reported, however, until recently, when partition chromatography became available as an analytical procedure for the a...

Desulfovibrio of the sheep rumen.

A sulfate-reducing bacterium has been isolated in pure culture from sheep rumen contents. Its properties agree in all respects tested with those ascribed to Desulfovibrio desulfuricans. The populations observed (about 10(8)/ml) are sufficient to account for published rates of ruminal sulfide production.
