The alpha helix and beta pleated sheet represent the secondary structure of proteins. Both structures are formed by the interaction of amino acids within the polypeptide chain through hydrogen bonding.
Yes, amylase contains both alpha helices and beta pleated sheets in its secondary structure. These structures are important for maintaining the enzyme's functional conformation and catalytic activity.
secondary protein structures formed by hydrogen bonds between the amino acids in a protein chain. They play a crucial role in determining the overall structure and function of proteins.
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.
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 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.
Alpha keratin has alpha helix structure and beta keratin has beta pleated sheet structure.
The alpha helix and beta pleated sheet represent the secondary structure of proteins. Both structures are formed by the interaction of amino acids within the polypeptide chain through hydrogen bonding.
secondary structure
In proteins, the alpha helix predominantly twists in a right-handed direction.
together they make a secondary protein structure
There are no known proteins such as helix proteins. Alpha helix is a secondary structure element found in proteins that formed by amino acids which can form helix. Other secondary structures are beta sheets and random coils.
The secondary structures of alpha helix and beta pleated sheets are formed by hydrogen bonding between amino acids in a protein chain. In an alpha helix, the hydrogen bonding occurs between amino acids in the same chain, leading to a helical structure. In beta pleated sheets, hydrogen bonding occurs between amino acids in different segments of the protein chain, creating a sheet-like structure.
Proteins can form structures such as a helix or a sheet due to the specific arrangement of amino acids in their sequence. The hydrogen bonding between the amino acids in the polypeptide chain determines the secondary structure of the protein, leading to the formation of helices and sheets.

secondary protein structures formed by hydrogen bonds between the amino acids in a protein chain. They play a crucial role in determining the overall structure and function of proteins.
Hydrogen bonding is the primary interaction that stabilizes the alpha helix and beta pleated sheets of a protein. In the case of alpha helices, hydrogen bonds form between the carbonyl oxygen of one amino acid residue and the amide hydrogen of another residue in the chain. In beta sheets, hydrogen bonds form between adjacent strands of the sheet.
