    Good evening, i have had great help(piggy) from this website in the past and hopefully this will not be the exception.
    I am currently stuck trying to find out how the structure of collagen helps fulfil its function. If there is anyone out there that could shed some light on this i would greatly appreciate it. You will have my eternal thanks.
    Without sticking the hand in, i could use help with antibodies swell if there is any help going.
    Thank you

    Just quoting in Puddles the Monkey so she can move the thread if needed
    (Original post by Puddles the Monkey)

    - Collagen molecules have three polypeptide chains wound around each other in a triple helix structure to from a tough, rope like protein.
    -Many hydrogen bonds from between the polypeptide chains forming a long quaternary proteins with staggered ends. These allow the proteins to join end to end, forming long fibrils called tropocollagen. The tropocollgens fibrils cross link to produce strong fibres which is why this structure that are found in ligaments and tendons.

    Hope that helped.
