Abstract

Helix probability profiles are calculated for collagen models that take into account specific sequence and unwinding from the ends, by internal loops and by chain dissociation, using parameters from a previous study and the technique of the previous paper.^2^ An analysis is made of the occurrence of imino acids in known collagen sequences and no significant difference is found from random occurrence. Studies of model sequences generated by random placement of the imino acids show no tendency for collagen to unwind via internal loops even when one end is covalently linked and a loop is permanently nucleated at that end.
