p-Hydroxybutyrate and Acetate Metabolism of the Perfused Bovine Udder*
It was established by Shaw and Knodt (I) that the normal lactating udder (in situ) of the cow utilizes almost 2 mg. of phydroxybutyric acid per 100 ml. of blood traversing the udder; it was calculated that this was sufficient to account for the short chain fatty acids of milk fat or for about 40 per cent of the oxygen consumption of the secreting gland if it were oxidized for energy purposes. L...

متن کاملThe metabolism of acetate and glucose by the isolated perfused udder. 2. The contribution of acetate and glucose to carbon dioxide and milk constituents.
Recent work has emphasized that both glucose and acetate are important metabolites in the ruminant. Annison & Lindsay (1961) estimate that 33 % of expired C02 is derived directly from acetate in the fed sheep, and Annison & White (1961) find that, under these conditions, 23 % comes from glucose; both these values are sensitive to the nutritional state of the animal. Considerable quantities of b...
متن کاملMetabolism of γ-hydroxybutyrate in perfused rat livers.
GHB (γ-hydroxybutyrate) is both a neurotransmitter and a drug of abuse (date-rape drug). We investigated the catabolism of this compound in perfused rat livers. Using a combination of metabolomics and mass isotopomer analysis, we showed that GHB is metabolized by multiple processes, in addition to its previously reported metabolism in the citric acid cycle via oxidation to succinate. A substrat...
متن کاملSynthesis of milk fat from acetic acid (CH3 14COOH) by the perfused isolated bovine udder.
The technique of perfusion of the isolated udder is likely to give valuable information on the mechanisms of milk formation, provided it can be shown that most of the milk collected is actually a product of the secretory activity of the gland during the experiment. This point is not easy to demonstrate by ordinary chemical methods, because present-day techniques only permit of a rather limited ...
