(Phys.org) —A key feature of certain chemicals is their ability to bind to other molecules – a property that emerged through evolution – but current chemical theory lacks the ability to design binders from first principles. ...
(PhysOrg.com) -- To study the behavior of large protein complexes and long DNA chains in solution, researchers use so-called molecular traps. However, earlier traps have proven ineffective when working with small molecules ...
Humans need oxygen molecules for a process called cellular respiration, which takes place in our cells' mitochondria. Through a series of reactions called the electron transport chain, electrons are passed along in a sort ...
