24. A secondary level protein consists
of simple loops or coils of a single polypeptide chain with occasional hydrogen
bonds formed between amino acids in the chain that are non-adjacent.
A tertiary level protein consists of
a complex series of loops or coils of a single polypeptide chain.
The chain on the left represents a secondary level protein
as it is a simple coil or folding of the polypeptide chain. The figure on the
right represents a tertiary level protein of more complex coiling or folding
in several different planes.
