What are two major types of protein secondary structure, and what kind of interaction holds them together , and between what part of the protein do they occur?
Homework Answers
Two major type of secondary protein structure is present in alpha-helices and beta sheets.
Hydrogen bonding between the atoms in the peptide bonds along the chain holds the backbone together.
In an alpha helix, one sheet of C terminal amino acid sheet is parallel to the one N-terminal amino acid chain, shown in the above figure.
A beta helix is a protein structure formed by the association of parallel beta strands where both backbones of the protein chain are not parallel.

Predict what would happen to the secondary structure of a protein if an alcohol that disrupts hydrogen bonding were added. Choose one or more answer (if applied): A. Nothing would happen to the protein; hydrogen bonding is not important for secondary structure B. The beta sheets would unfold, disrupting protein structure C. The a helixes would unfold, disrupting protein structure D. Individual amino acids would be hydrolyzed from the protein, disrupting protein structure
