Recent advances in the biosynthesis of unusual polyketide synthase substrates

Polyketides comprise a diverse class of natural products, with many important biological and pharmacological activities. Substrates functioning as starter units and extender units during their assembly significantly contribute to the chemical complexity exhibited by this class of natural products. This highlight provides an overview of the recent advances in understanding the diversity of these polyketide synthase (PKS) building blocks.

The intrinsic nanofibrillar morphology of polyaniline

Nanofibrillar morphology is found to be intrinsic to polyaniline chemically synthesized in water. In conventional synthesis (left), the product that readily precipitates out of the solution is a mixture of irregularly-shaped, micron-sized particulates and nanofibers. In interfacial polymerization (middle) and rapidly-mixed reactions (right), the products are pure nanofibers that disperse very well in water.

Is food allergen analysis flawed? Health and supply chain risks and a proposed framework to address urgent analytical needs

Food allergy is an increasing problem. If we fail to realise the promise of current risk assessment and risk management of food allergens through lack of ability to measure them reproducibly and with traceability to an international unit of measurement, the analytical community will have failed a significant societal challenge.
