A spectroscopic study of the cis/trans-isomers of penta-2,4-dienoic acid attached to gold nanoclusters.
In this theoretical work, we present a spectroscopic analysis of the cis/trans-isomers of a molecular switch, penta-2,4-dienoic acid, attached to gold clusters of different size (1, 2 and 20 gold atoms). We have simulated 4 different spectroscopic techniques: Infrared spectroscopy, normal Raman scattering, absorption spectra and resonance Raman scattering. We discuss how the position and the co...
متن کاملPyrenophoric acid, a phytotoxic sesquiterpenoid penta-2,4-dienoic acid produced by a potential mycoherbicide, Pyrenophora semeniperda.
A new phytotoxic sesquiterpenoid penta-2,4-dienoic acid, named pyrenophoric acid, was isolated from solid wheat seed culture of Pyrenophora semeniperda, a fungal pathogen proposed as a mycoherbicide for biocontrol of cheatgrass (Bromus tectorum) and other annual bromes. These bromes are serious weeds in winter cereals and also on temperate semiarid rangelands. Pyrenophoric acid was characterize...
متن کاملReaction of prostaglandin endoperoxide synthase with cis,cis-eicosa-11,14-dienoic acid.
The pre-steady-state phase of the oxygenase reaction of prostaglandin endoperoxide synthase with cis,cis-eicosa-11, 14-dienoic acid has been studied using stopped flow techniques. Because some intermediate forms of prostaglandin endoperoxide synthase are spectrally indistinguishable, the enzyme and substrate transformations were monitored in parallel to simplify the interpretation of the kineti...
متن کاملdiethylenetriamine penta-acetic acid
The chelating agent diethylenetriamine penta-acetic acid was used to measure iron stores in 83 patients with chronic liver disease. Iron chelation was normal in patients with chronic cholestasis. Chelation was increased above the control range in 14 out of 26 patients with alcoholic cirrhosis, in nine out of 28 patients with non-alcoholiccirrhosis, and in 11 out of 15 cirrhotics with a portacav...
متن کاملMammary cancer prevention by conjugated dienoic derivative of linoleic acid.
Conjugated dienoic derivative of linoleic acid (CLA) is a collective term which refers to a mixture of positional and geometric isomers of linoleic acid. It is a naturally occurring substance in food and is present at higher concentrations in products from animal sources. The present study reports that synthetically prepared CLA is an effective agent in inhibiting the development of mammary tum...
