Researchers Observe Picosecond Charge Transfer in Peptides Written by AZoMApr 15 2021 The transfer of electrons between molecules forms the basis of biological energy flows, for example, in photosynthesis and respiration. The extended peptide (top) does not mediate charge transfer (detectable charge transfer). The folded peptide (bottom) mediates picosecond charge transfer along the hydrogen bonds between the donor and the acceptor (the hydrogen bonds are indicated with thin red dotted lines).

 E-Mail Biological energy flows, such as in photosynthesis and respiration, depend on the transfer of electrons from one molecule to another. Despite its importance to sustaining life, factors governing the rate of electron transfer, especially over long distances, are not well understood because the systems that mediate such ultrafast processes are very complex. A better understanding of electron transfer rates would help scientists improve chemical transformations, energy conversion, electronic devices, and photonic technologies. Now, an international team of researchers led by UC Riversi...
