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 ...

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 ...

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 ...
