When bones are boiled in water over extended periods, heat disrupts the hydrogen bonds stabilising the collagen fibrils , causing them to unravel. This process, known as thermal denaturation , leads ...

if you took three of the cyclically hydrogen bonded chains out of the lattice and simply put pyrrolidine rings in positions two and three, you would have a model for collagen, because at that time ...

Having 'solved' the structure of polyglycine II in August of 1955 1, Alex Rich and Francis Crick realize, a month later, that they are now in a position to build a model of the structure of ...
