The Absorption of Soluble, Volatile Fatty Acids*
Experimental investigations show clearly that the absorption and metabolism of the short chain, water-soluble fatty acids differ in some way from those of the long chain fatty acids insoluble in water. Experiments by Lebedeff (1883), Leube (1895), Zunts (1901), and Eckstein (1929) show no evidence of the butyryl radical in the deposited fat when fed either as a fat or in the form of tributyrin....
متن کاملOrigin and utilization of volatile fatty acids in the rat.
The arteriovenous differences in the caecum of the rat have been compared for volatile fatty acids (VFA) and for electrolytes. Our results suggest the possibility of an exchange between VFA and chloride at the level of the caecal wall, rather than a net exchange between VFA and bicarbonate; however, the role of bicarbonate or Cl- at the cellular level is still unknown. Acetate uptake by the liv...
متن کاملThe absorption of volatile fatty acids from the rumen.
The fermentation of carbohydrates in the rumen of sheep is known to lead to the formation of large amounts of the lower fatty acids. The important part that these acids assume in the metabolism of ruminants has been remarked upon (Marston, 1939, 1946). While it is believed that acetic, propionic and butyric acids are the main fatty acid products of the fermentation, there is no certain knowledg...
متن کاملTHE ABSORPTION OF VOLATILE FATTY ACIDS FROM THE RUMEN II. THE INFLUENCE OF pH ON ABSORPTION
In a previous paper the relative rates of absorption of acetic acid and propionic acid through the rumen wall were discussed (Gray, 1947a). While the manuscript was being prepared, Danielli, Hitchcock, Marshall & Phillipson (1945) described a series of experiments from which it was evident that the lower homologues of the fatty acids are absorbed through the rumen wall at different rates when t...
متن کاملUtilization of volatile fatty acids and glucose for protein deposition in lambs.
I . Glucose, and acetic, propionic and butyric acids, the major energy sources available to ruminants, have been comparatively evaluated as energy sources for growth in lambs. The energy sources wcrc administered intravenously at 2.092 and 2. j 10 MJ metabolizable energy per 24 h for periods of 9-12 d. Nitrogen was given in excess of requirement so that growth rate was limited by energy, as ind...
