Valine Ameliorates Liver Fibrosis
It has been reported that treatment with branched chain amino acids (BCAAs) increases the survival rates in cirrhotic patients. In this study, we investigated the effect of L-valine, one of BCAAs, on liver fibrosis in rat. To induce liver fibrosis, male Wistar rats were injected carbon tetrachloride (CCl4) intraperitoneally (2.0 mL/kg) twice a week for 12 weeks. The rats (seven to fifteen rats ...
متن کاملValine for Lactation
An experiment was conducted using production and metabolic criteria to estimate the valine requirement of the lactating sow. Ground corn, gelatin, corn sugar, vitamins, minerals and indispensable amino acids were used to formulate a diet containing all the essential nutrients except valine. L-valine was added to provide .23 (basal), .38, .53, .68 and .83% valine. Twenty-five mature Landrace • Y...
متن کاملBiosynthesis of Valine and Isoleucine
The isotope studies of Strassman et al. (3, 4) first implicated cu-acetolactate and cu-aceto-cY-hydroxybutyrate as biosynthetic precursors of valine and isoleucine, respectively. The observed accumulation of acetolactate by Escherichia coli (5, 6) and of the decarboxylation products of acetolactate and acetohydroxybutyrate by Neurospora crassa (7) when mutants of these organisms are grown with ...
متن کاملValine requirement of nursery pigs.
Six experiments were conducted to determine the true digestible valine requirement of 5- to 20-kg pigs. In Exp. 1, a valine-deficient diet for 5- to 10-kg pigs was developed and validated in terms of growth performance in response to supplemental L-valine. A different basal diet was validated for 10- to 20-kg pigs in Exp. 2. Both diets were demonstrated to be deficient in valine and to support ...
متن کاملBiosynthesis of Valine and Isoleucine
Evidence published in recent years has shown that the biosynthesis of valine and isoleucine proceeds by a similar sequence of reactions (24). Fig. 1 depicts the reactions considered to be involved. In this report only Reactions II, III, and IV will be considered. Reaction II, the isomerization of the Lu-hydroxy$keto acid (ac-acetolactate for valine biosynthesis and a-aceto-a-hydroxybutyrate for...
