WebJul 1, 1974 · The dethiomethylation of methionine by a dialyzed extract obtained from the protozoa-rich fraction of rumen fluid is stimulated 2.5-fold by pyridoxal phosphate and strongly inhibited by deoxypyridoxine, a pyridoxal phosphate antagonist. These effects are not seen with undialyzed extracts or with whole rumen fluid. WebJan 24, 2024 · A new one-pot three-component reaction for the synthesis of indolyl-4H-chromene derivatives has been developed. The synthesis was achieved by reacting salicylaldehydes, (E)-N-methyl-1-(methylsulfanyl)-2-nitroethenamine, and indoles in the absence of solvent using triethylamine as a catalyst. The final products were isolated by … WebIncubation of rumen fluid for short periods (5 hours) with various sulfur compounds resulted in the accumulation of methanethiol and dimethyl sulfide in the headspace above the fermentation mixture.
