Proton transfer process in living systems was thought to occur by jumping from water molecule to water molecule and between chains of amino acids, but recent research has shown that protons transfer along with electrons, which are linked to electron spin and quantum mechanics.
Scientists in Israel confirmed that proton movement is connected to electron spin through chiral induced spin selectivity using crystals of lysozyme enzyme placed on a magnetic substrate.
The coupling between proton transfer and spin-selective electron transfer was found to influence proton movement, indicating a relationship between proton transfer and electron spin.
The study's findings could potentially enhance the understanding of information and energy transfer inside living cells and shed light on the role of chirality in biological processes, highlighting the fundamental relation between quantum physics and biochemistry.
