| The carbon molecules in coal-derived fuels form rings that join into chainlike molecules a called cycloalkanes, while petroleum fuels have mainly linear molecules. |
| Linear polymers are long, chainlike molecules covalently bonded in a rigid manner. |
| Chitosan is a long, chainlike molecule and these molecules are laid out in an extended, linear fashion to form fibers. |
| So when a jam mixture cools, the chainlike pectin molecules bond to form a network, holding the sugar solution and fruit pulp in what appears to be a solid mass. |
| Long, chainlike protein molecules fold up spontaneously and flawlessly into predetermined shapes. |
| Thus, the magnetic particles form special chainlike structure in the direction of the magnetic field, which results in the controllable shear modulus with the magnetic fields. |
