Davydov's theory of solitons as a mechanism for energy storage and transport in protein. Particular attention is paid to the construction of quantum states that contain N amide-I vibrational quanta. It is noted that the 'N = 2' state is almost exactly resonant with the free energy that is released upon hydrolysis of adenosine triphosphate. 1. philips trimmer online shop https://loudandflashy.com
