Question

An amino acid on a protein strand forms a hydrogen bond to another amino acid that is 4 amino acid units away. The next amino acid on the chain does the same, hydrogen bonding to an amino acid that is 4 amino acids away from it. This pattern repeats itself over a significant part of the protein chain.

Part A

The resulting pattern in the protein is an example of what kind of structure (primary, secondary, tertiary, or quaternary)?

The resulting pattern in the protein is an example of what kind of structure (primary, secondary, tertiary, or quaternary)?

Explanation / Answer

Secondary structure: (alpha helix)

Secondary structure can be formally defined by the pattern of hydrogen bonds of the protein (such as alpha helices and beta sheets)
