These molecules were not present on early earth, however other amphiphilic long chain molecules also form membranes.

However, it is important to ensure that chain molecules are oriented across the hinge to maximise strength.

This technology is practiced on a large scale to produce longer chain molecules than methane.

Biotronic information units would only be as big as chain molecules.

Both operate by breaking down the very long chain molecules that give polymeric plastics their strength.

This breaks down swiftly as compared to polypropylene, a long chain molecule.

In other words Kramers problem for the long chain molecule.

These proteins are long chain molecules made up of simple building blocks called amino acids.

Polymers are long chain molecules that tend to be entangled with one another.

"The oil is absorbed into the polymer and joins in long chain molecules to form a sheet of rubber," he said.
