It can be seen that ©ach follows a helical path, having a left-handed 3-fold screw axis# (The axes are shown symbolically as vertical lines)• The broken lines between the two chains represent hydrogen bonds. The larger circles represent the C carbon atoms* ^ ^ I * I Pig. 2 a simplified version of Pig. 1, in which o ni: the C a carbon atoms are shown, connected by short straight lines symbolizing the peptide groups. The broken lines represent hydrogen bonding. Pig. 3 As' Fig. 2, but with a third polypeptide chain added behind the other two. This arrangement is related to Collagen I. The numbers 1, 2 and 3 represent the three types of side-chain positions. Broken lines represent hydrogen bonds. Fig. k Â8 Fig, 2, out with a third polypeptide chain added in front of the other two. This arrangement is related to Collagen II. The numbers 1, 2 and 3 re,; resent the three types of side-chain positions. Broken lines represent hydrogen bonds. Fig. 5 Showing the general way in which the structures of Figa. 3 and h are deformed to give the Colla gen modes# The solid lines
