Enzyme Reactions with Phenolic Compounds: Formation Hydroxystyrenes through the Decarboxylation of PHydroxycinnamic Acids by Aerobacter*
A constitutive enzyme present in strains of Aerobacter has been found to decarboqdate phenylacrylic (cinnamic) acids possessing a 4-hydroxy group to the corresponding hydroxystyrenes nonoxidatively. Two such products, 4-hydroxystyrene (4-vinylphenol) and 3 ,Cdihydroxystyrene (4-vinylcatechol) from p-coumaric and caffeic acids, respectively, were purified and identified. Only 4-hydroxystyrene ha...
متن کاملHydrothermal decarboxylation and hydrogenation of fatty acids over Pt/C.
We report herein on the conversion of saturated and unsaturated fatty acids to alkanes over Pt/C in high-temperature water. The reactions were done with no added H(2) . The saturated fatty acids (stearic, palmitic, and lauric acid) gave the corresponding decarboxylation products (n-alkanes) with greater than 90 % selectivity, and the formation rates were independent of the fatty acid carbon num...
متن کاملAcceleration of Renal Gluconeogenesis by Ketone Bodies and Fatty Acids.
1. Acetoacetate or short-chain fatty acids (acetate, butyrate, propionate, n-hexanoate, n-octanoate) accelerate the rate of glucose formation from lactate, fumarate and other precursors in slices of kidney cortex (rat, rabbit, sheep). The cause of this acceleration has been investigated. 2. There are two different mechanisms of acceleration. At low concentrations of glucogenic precursors the ac...
