QUANTUM CORRECTION. "In enzyme catalysis, a large portion of the quantum improvement over the classical catalytic rates could be attributed to the zero-point energy that gives a quantum correction to the barrier height and the hydrogen tunnelling rates." https://lnkd.in/eRUdQZj View in LinkedIn

QUANTUM ENZYMES. "Hydrogen tunnelling also plays an important role in a wide range of biological enzymatic catalytic reactions. Observations of strong intrinsic kinetic isotope effects in enzymatic reactions have clearly demonstrated nuclear quantum effects in enzymes." https://lnkd.in/eRUdQZj View in LinkedIn

PERPLEXING PROTEIN TUNNELING. "It is remarkable that such long-distance electron transfer in biology occurs through quantum mechanical tunnelling, because electron tunnelling over such long distances would be impossible in vacuum." https://lnkd.in/eRUdQZj View in LinkedIn

CULTURE GAP: PHYSICS AND BIOLOGY. "Biology today is where physics was at the beginning of the twentieth century...It is faced with a lot of facts that need an explanation..."What has been all too rare in biology is the symbiosis between theory and experiment that is routine in physics." https://lnkd.in/eVFhtfq View in LinkedIn

"LONG-RANGE ELECTRON TRANSFER through proteins often show exponential distance dependence as well as weak temperature dependence, providing a strong indication that a single-step tunnelling mechanism is responsible for these biological processes." https://lnkd.in/eRUdQZj View in LinkedIn

HAPPY NEW YEAR. Humans have a long way to go not to simply be a planetary menace, or as Attenborough said "a scourge upon the earth". View in LinkedIn

ENZYME QUANTUM TUNNELING. "Researchers have known for several years that in some enzyme-catalysed reactions, protons move from one molecule to another by the quantum-mechanical phenomenon of tunnelling, in which a particle passes through an energy barrier rather than having to muster the energy to climb over it." https://lnkd.in/eDJed9B View in LinkedIn

"ELECTRON TRANSFERS between the proteins of the cellular respiratory chains occur over ca. 10-20 Å and are usually assumed to follow the coherent super-exchange mechanism. When some molecular fragment(s) are susceptible to host the electron (or a hole) transiently on the way to the acceptor (donor) site, multistep (incoherent) hopping is likely to be the dominant mechanism." https://lnkd.in/eMTJFEQ View in LinkedIn

"ENZYMES can employ a weird quantum trick called tunnelling. Simply put, the enzyme encourages a process whereby electrons and protons vanish from one position in a biochemical and instantly rematerialise in another, without visiting any of the in-between places – a kind of teleportation." https://lnkd.in/eYXPebN View in LinkedIn

UNCANNY WATER. "Microtubule nanotubes are found in every living eukaryotic cells; these are formed by reversible polymerization of the tubulin protein, and their hollow fibers are filled with uniquely arranged water molecules. Water channel inside microtubule does a mysterious job that enables microtubules with 40,000 tubulins to demonstrate conductivity 1000 times more than the single tubulin protein." https://lnkd.in/e27q_UB View in LinkedIn
