Using muon spin rotation spectroscopy, researchers from Japan and Canada successfully captured the rapid conversion of an ...

The Diels-Alder reaction, a widely used transformation in organic synthesis, forms six-membered rings from a conjugated diene and a dienophile-frequently an alkene. Usually, these two reactants must ...

The polysaccharide β-1,2-glucan consists of repeating units of glucose linked together by β-1,2-glycosidic bonds. Cyclic β-1,2-glucans (CβGs) occur in different bacterial species and have a role in ...

Cyclic tetrapeptides comprise a potent and selective class of molecules with a wide range of biological activities, including the phytotoxic activity of tentoxin and the histone deacetylase (HDAC) ...

SOME MARINE organisms have a knack for making steroidal compounds containing halogens. Chemists have long tried to do the same thing, because such compounds can be useful, for example, in treating ...

Many different mechanisms have been suggested for the oxidative lipid fragmentations that produce biologically active aldehydes such as 4-hydroxynon-2-enal (HNE), oxononanoyl phosphatidylcholine ...
