What level of protein structure is associated the alpha helix and beta pleated sheet?

It depends on the primary sequence of amino acids as to which secondary structure is more stable. Both structures use hydrogen bonds to stabilize the structures, however in an alpha helix, these hydrogen bonds are with the peptide and in beta sheets the hydrogen bonds are between beta peptide strands.
I really don't know which structure is more stable...
-alpha helix seems to be a more common structure
-and B sheets lose some H bonding during hair pin turns and during twists.
-But an alpha helix has a dipole whereas an antiparalle beta sheet doesnt.
-weighing it up i would assume an alpha helix to be more stable but that would be a guess from me.

The alpha helix and pleated sheet are examples of?
secondary structure of a protein
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
Do amino acids contain alpha and beta pleated sheet in their secondary structure?
Yes, they do. Side group hydrogen bonding.
What is the tertiary structure for a protein?
'The Quaternary structure of a protein is the 4th level of folding for a protein. An example of this would be a red blood cell, which is a quaternary structure, it is made up of alpha helicies and also beta pleated in the tertiary structure. The Quaternary structure of a protein contains 4 tertiary structures in it.
What is the four levels of proteins?
Proteins have primary structure, which is their amino acid sequence, secondary structure, which is either the alpha helix or the beta pleated sheet, tertiary structure, the protein's geometric shape, and quaternary structure, the arrangement of multiple protein subunits.
The alpha helix and pleated sheet are examples of?
secondary structure of a protein
What type of protein shape is characterized by the alpha helix or a flat-pleated sheet?
secondary structure
What does Alpha helix and beta pleated sheets make up?
together they make a secondary protein structure
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
Do the coils and folds of a protein's amino acid chain make up the protein's primary structure?
The coils of an alpha helix or the folds of a beta-pleated sheet are a characteristic of the secondary structure.
Structure of keratin?
Alpha keratin has alpha helix structure and beta keratin has beta pleated sheet structure.
Name two types of secondary protein structure Explain the role of hydrogen bonds in maintaining secondary structure?
alpha Helix and Beta pleated sheet
What are the two most common secondary structures in a protein?
The two types of tertiary protein structures: globular and fibrous proteins. Globular proteins act as enzymes that catalyze chemical reactions in organisms. Fibrous proteins like collagen play structural role.
What can form a structure such as a helix or a sheet?
A polypeptide chain, which is the primary structure of a protein, can fold into secondary structures such as an alpha-helix or a beta-sheet.
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 level of protein structure is represented by the coiling of the protein chain backbone into an alpha helix?
The coiling of the protein chain background into an alpha helix is the secondary structure. This is caused by the H-bonded arrangement of the backbone of th protein.
Does the secondary structure of a protein involve only the sequence of amino acids found in that protein?
While it is possible to predict likely secondary structures of a protein from its primary structure, only knowing the secondary structure, the general 3-D shape of local areas of the protein, cannot yield the primary structure.
