One secondary structure, α helix, is a delicate coil held together by hydrogen bonds every 4th amino acid. A structure with α helix is keratin, the material the human body uses to produce hair. The other secondary structure is β pleated sheet. In this one, two or more strands of β strands are connected by hydrogen bonds between parts of two parallel polypeptide backbones. This secondary structure is what spider webs are made of, and the hydrogen bonding makes it stronger than a strand of steel of the same weight. These secondary structures are unable to be formed without hydrogen bonding.

Name two types of secondary protein structure Explain the role of hydrogen bonds in maintaining secondary structure?
alpha Helix and Beta pleated sheet
What level of protein structure is a spatial arrangement of the secondary structure?
hydrogen bonds
Describe polymeric structure of hydrogen fluoride?
For the structure of hydrogen fluoride (HF) see the link bellow.
What aspect of protein structure are stabilized or assisted by hydrogen bonds?
secondary, tertiary, and quaternary structures, but not primary structure
What structural level of a protein most affected by a disruption in hydrogen bonding?
The structural level of a protein is most affected by disruption would be the secondary structure. It is within the secondary structure where the folding and coiling of the protein is stabilized by hydrogen bonds.
What bonds hold the secondary structure of protein together?
regularly spaced hydrogen bondings
Hydrogen bonds between different parts of the polypeptide chain result in which level of protein structure?
Tertiary structure
What causes the secondary structure of protein to differ in length from the primary?
The primary structure is a one or two dimensional structure, whereas the secondary structure is a three dimensional structure in which different parts of the protein molecule bend and twist due to the formation of hydrogen bonds between atoms. This makes the secondary structure shorter than the primary structure.
What does the secondary structure of a protein result from?
The secondary structure of a protein results from hydrogen bonds.
Differentiate between secondary and tertiary structure by describing the parts of the polypeptide chain that participates in the bonds that hold together each level of structure?
Secondary tertiary is the R groups interactions that are ionic. The polypeptide chain also has disulfide bond, and hydrophobic interactions.
What is distinctive about primary vs secondary protein structure?
The primary structure of a protein is just an amino acid string; a polypeptide. The secondary structure of a protein is the hydrogen bonding of the side chains that form the polypeptide chain into alpha helices and beta sheets.
Some regions of a polypeptide may coil or fold back on themselves?
secondary structure ,hydrogen bonds
