What type of interaction stabilizes the secondary structure of a protein causing it to form an alpha-helix?
Wiki User
∙ 7y ago
In an α-helix, the polypeptide backbone forms a repeating helical structure that is stabilized by hydrogen bonds between a carbonyl oxygen and an amine hydrogen. These hydrogen bonds occur at regular intervals of one hydrogen bond every fourth amino acid and cause the polypeptide backbone to form a helix.

The alpha helix and beta pleated sheet represent which level of protein structure?
The alpha helix and beta sheets are found at the Secondary level of protein folding. It's when the protein is taking its shape. Secondary structure
Is the secondary structure more polar than the linear amino acid sequence?
Protein tertiary structure is 3-D. Secondary structure is 2-D or linear. I. e. the linear a-a sequence is the secondary structure. Amino-acid monomers comprise the primary structure.
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.
What is cytosquelette?
A dynamic structure that stabilizes cells lacking a cell wall (=animal cells). It consists out of microtubules, intermediate filaments and actin filaments.
Why is DMSO used in PCR?
reduce secondary structure
Differentiate the four types of protein structure?
There are four types of protein structure. These include primary structure, secondary structure, tertiary structure, and quaternary structure. Primary structure is the amino acid sequence. Secondary structure is the shape of the molecule. Tertiary structure is the interaction between groups. Quaternary structure is the interactions between protein subunits.
Bond stabilizes protein folded 3D structure and DNA double helix 3D structure?
non polar bond
Is collagen a secondary or tertiary structure?
With most proteins, it has a secondary and 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.
Why is secondary called secondary?
Proteins *have* primary, secondary, tertiary, and quarternary structures. The primary structure is simply the chain of amino acids without any other structure. Secondary structure results from folding of the chain to form rudimentary structures such as alpha helices, beta sheets and turns. Tertiary structure results from the further folding of the protein with secondary structures into different 3D shapes by interactions between different parts of the secondary structure. Quarternary structure results from different proteins with tertiary structures coming together to form a protein complex.
Secondary protein structure?
The secondary structure of protein:the ordered 3-d arrangements in localized area of a polypeptide chaininteractions of the peptide backbone (s-trans and planar)example of secondary structure : alpha-helix and beta-pleated sheet
What is the coiling or sheetlike structure of a protein called?
It is called secondary structure of proteins .
What level of protein structure is a spatial arrangement of the secondary structure?
hydrogen bonds
What is cytosquelette?
A dynamic structure that stabilizes cells lacking a cell wall (=animal cells). It consists out of microtubules, intermediate filaments and actin filaments.
