The reaction of a readily obtained chiral branched homoprenylamonium salt with a range of aldehydes, including aliphatic substrates, affords the corresponding linear isomers in good yields and enantioselectivities.

The World Health Organization promotes salt reduction as a best-buy strategy to reduce chronic diseases, and Member States have agreed to a 30% reduction target in mean population salt intake by 2025. Whilst the UK has made the most progress on salt reduction, South Africa was the first country to pass legislation for salt levels in a range of processed foods. This paper compares the process of...

Solubilization of phosphatidylinositol (PtdIns) synthase (CDP-diacylglycerol: myo-inositol 3-phosphatidyltransferase, EC 2.7.8.11) from rat pituitary (GH3) tumours was investigated. PtdIns synthase activity was partially extracted from crude membranes by 3 M-KCl. Prior separation of membranes revealed that a greater proportion of plasma-membrane PtdIns synthase activity was salt-extractable tha...

in many studies, the medicinal properties and impact of blond plantain on mechanisms of human physical activities has been proven. salinity is an important abiotic stresses with detrimental effects on seed germination. an experiment was conducted to study germination characteristics of blond plantain under water and salinity stress conditions at different temperatures. the experiment was conduc...

Facile evaluation of mixed-salt effect on the strongly salt-dependent thermodynamic and kinetic parameters of protein-DNA complexes is of importance for relevant biochemical and biophysical studies. In pursuit of this aim, binding isotherms for open transcription complex (RPo) of Escherichia coli RNA polymerase (R) at lambdaP(R) promoter DNA (P) were determined as a function of salt concentrati...

In the last 500 million years, Earth's biota experienced periods of crises with extinctions on a large scale and significant turnover events, one them being Permian/Triassic boundary extinction event. The following Early Triassic was critical time marked by series biological environmental changes complex recovery pattern marine faunas ecosystems. Generally, animals plants respond to stress usin...

BACKGROUND In Rajasthan, an Indian State with significant salt production, the sale of non-iodized salt for human consumption was banned in 1992. This study explored the relationships between the use of iodized salt in Rajasthan and the iodine status of children and pregnant women living in the area. METHODS In a State-wide survey, 30 clusters were selected proportionate-to-population-size an...

We describe a class of zwitterionic sulfobetaine (SB) lipids with fascinating salt-dependent properties. SB lipids are zwitter-neutral across a broad pH range; however they have negative surface potentials in the presence of anions and two salt-dependent transition temperatures. These new SB lipids provide insight on the role of charge orientation at the membrane interface and may be useful com...
