Ruminal degradation of quercetin and its influence on fermentation in ruminants.

J. Dairy Sci. 98 , 5688-98, (2015)

The aim of the present study was to investigate the ruminal degradation of the flavonol quercetin and to determine its potential antimicrobial effects on ruminal fermentation in cows. Ruminal degradation of quercetin (0 or 100μmol/L, respectively) as well as ...

Physical Properties, Volatiles Compositions and Sensory Descriptions of the Aromatized Hazelnut Oil-Wax Organogels.

J. Food Sci. 80 , S2035-44, (2015)

The purpose of this study was to determine the physicochemical, thermal and sensorial features of vitamin enriched and aromatized hazelnut oil-beeswax and sunflower wax organogels. Another objective was to monitor the influence of storage on textural and oxid...

Internal standards for gas chromatographic analysis of metabolic end products from anaerobic bacteria.

Appl. Environ. Microbiol. 33(4) , 1002-3, (1977)

2-Methylpentanoic acid and benzoic acid are suggested for use as routine internal standards for gas chromatographic analysis of microbial end products.

Propionyl-CoA condensing enzyme from Ascaris muscle mitochondria. I. Isolation and characterization of multiple forms.

Arch. Biochem. Biophys. 285(1) , 158-65, (1991)

The condensation of two propionyl-CoA units or a propionyl-CoA with acetyl-CoA is required for the synthesis of 2-methylvalerate or 2-methylbutyrate, respectively, two of the major fermentation products of Ascaris anaerobic muscle metabolism. An enzyme that p...

Additive incidence of developmental malformation for Xenopus embryos exposed to a mixture of ten aliphatic carboxylic acids.

Teratology 44(5) , 531-46, (1991)

A modified FETAX (Frog Embryo Teratogenesis Assay: Xenopus) protocol was used to assess the joint action of ten aliphatic carboxylic acids on Xenopus embryo development. Stock solutions of each acid alone, made up at twice the EC50 of the individual acids, we...

Biochemical changes during the aerobic-anaerobic transition in Ascaris suum larvae.

Mol. Biochem. Parasitol. 22(2-3) , 241-8, (1987)

Ascaris suum L3 larvae isolated from rabbit lungs undergo the third ecdysis to L4 larvae after 3 days in culture under a gas phase of 85% N2/10% CO2/5% O2. The L3 larvae contain substantial malic enzyme activity and are capable of producing small amounts of t...

Pathway of formation of branched-chain volatile fatty acids in Ascaris mitochondria.

J. Parasitol. 67(6) , 841-6, (1981)

Disrupted Ascaris mitochondria formed 2-methylbutyrate (2-MB) and 2-methylvalerate (2-MV) when incubated anaerobically with acetyl CoA, propionyl CoA and NADH. However, when mitochondrial membranes were removed by high speed centrifugation and the mitochondri...

Deglycobleomycin A6 analogues modified in the methylvalerate moiety.

Bioorg. Med. Chem. 19(12) , 3831-44, (2011)

Previous studies have indicated that the methylvalerate subunit of bleomycin (BLM) plays an important role in facilitating DNA cleavage by BLM and deglycoBLM. Eleven methylvalerate analogues have been synthesized and incorporated into deglycoBLM congeners by ...

Characterization of an archaeal medium-chain acyl coenzyme A synthetase from Methanosarcina acetivorans.

J. Bacteriol. 192(22) , 5982-90, (2010)

Short- and medium-chain acyl coenzyme A (acyl-CoA) synthetases catalyze the formation of acyl-CoA from an acyl substrate, ATP, and CoA. These enzymes catalyze mechanistically similar two-step reactions that proceed through an enzyme-bound acyl-AMP intermediat...
