Some commercially important vinyl derivatives are produced by the decarboxylation of phenolic acids. Enzymatically, this process can be achieved by phenolic acid decarboxylases (PADs), which are able to act on phenolic acid substrates such as ferulic and p-coumaric acid. Although many microbial PADs
Absence of a substantial pretracheophyte fossil record for bryophytes (otherwise predicted by molecular systematics) poses a major problem in our understanding of earliest land-plant structure. In contrast, there exist enigmatic Cambrian-Devonian microfossils (aggregations of tubes or sheets of
Quercetin (3,3',4',5,7-pentahydroxyflavone) is claimed to exert many beneficial health effects. With application of (1)H NMR (nuclear magnetic resonance) and FTIR (Fourier-transform infrared) techniques, quercetin interaction with liposomes formed with dipalmitoylphosphatidylcholine (DPPC) was
