The question should be "what do alpha helices and beta sheets create?" They form the tertiary structure of proteins.

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 aspect of protein structure are stabilized or assisted by hydrogen bonds?

secondary, tertiary, and quaternary structures, but not primary structure


What is the difference between interchain and intrachain hydrogen bonds in the secondary structure of proteins?

Interchain hydrogen bonds form between different protein chains, such as in a multimeric protein complex. Intrachain hydrogen bonds form within the same protein chain, stabilizing the secondary structure, such as alpha helices or beta sheets. Both types of hydrogen bonds contribute to the overall stability and structure of proteins.


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 structure refers to local folding patterns involving hydrogen bonding between the peptide backbone, forming alpha helices or beta sheets. Tertiary structure involves the overall 3D folding of the entire polypeptide chain, with interactions between side chains such as hydrophobic interactions, hydrogen bonding, disulfide bridges, and electrostatic interactions playing a major role in maintaining the structure.


Can silver be hammered into sheets?

Yes, silver can be hammered into sheets, a process known as silver sheet metalwork. The metal is heated to make it more malleable, then hammered using a technique known as planishing to create thin, flat sheets.

Can carbohydrates contain pleated sheets and helices?

No , these are present in proteins .


What can form a structure such as a helix or a sheet?

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.


What best describes how protein form?

Proteins are made up of amino acids that are linked together in a specific sequence. This sequence determines the three-dimensional structure of the protein, which is essential for its function. Proteins can fold into intricate shapes, such as alpha helices and beta sheets, through various interactions between amino acids, such as hydrogen bonds and hydrophobic interactions.


Which of these proteins in mammals show only primary and secondary structures?

Collagen and keratin are examples of proteins in mammals that primarily exhibit only primary and secondary structures. Collagen is known for its triple helix structure, while keratin is a fibrous protein that forms alpha-helices and beta-sheets.


What is the general shape of proteins of pleat?

Proteins generally fold into complex three-dimensional shapes, with a variety of structures such as helices, sheets, and loops. These shapes are essential for their function and can vary greatly depending on the specific sequence of amino acids in the protein.


Which strands is looped into domains by scaffolding?

In protein structure, the primary structure is the linear sequence of amino acids joined by peptide bonds that form a polypeptide chain. This chain then folds into secondary structures, such as alpha helices and beta sheets, which are further organized into tertiary structures or domains. Scaffolding proteins can facilitate the folding process by bringing different regions of the protein together, particularly in multidomain proteins.


Do all proteins have quandary structure?

No. Proteins start out as a Primary structure, which is just the linear form and sequence of amino acids. The proteins then start forming alpha helices and/or Beta sheets depending on the properties of the amino acids. This is their Secondary structure The proteins then fold completely into tertiary structure. Here, we have a lot of hydrogen bonding and hydrophobic interactions within the protein between the helices and beta sheets. Many proteins are fully functional in their tertiary structure and don't have any reason for forming into a quaternary structure. In the quaternary structure, we usually see an interaction between 2 or more polypeptides or proteins. An example would be 2 proteins in their tertiary structure binding together to become a functional dimer. If 3 proteins were interacting it would form a trimer. Several proteins are functional only in a quaternary structure while several more proteins are just fine in their tertiary structure and therefore do not have a quaternary structure.

What are the names and description of the four structures of proteins?

If meaning the four structural levels in proteins, then these are:* Primary structure, which is the sequence of amino acids in the peptide chain that constitutes the protein. * Secondary structure, is the location of formations called alpha-helices, beta-sheets and coiled coils (undefined, flexible structure), that forms with the help of hydrogen bonds between amino acids. * Tertiary structure: This is the over-all fold/structure of one peptide chain/protein, which can consist of many so called "domains" of typical structures of alpha-helices and beta-sheets. * Quaternary structure: Because some proteins are formed from many smaller subproteins (that is, by many peptide chains), quaternary structure describe how these subunits are assembled together.


What type of secondary structure does hemoglobin have?

Hemoglobin is a protein with a combination of secondary structures, predominantly consisting of alpha helices and beta sheets. These structural elements help maintain the shape and function of hemoglobin as a globular protein.


What is the role of secondary protein structures in determining the overall function of a protein?

Secondary protein structures, such as alpha helices and beta sheets, play a crucial role in determining the overall function of a protein. These structures help proteins fold into specific shapes, which are essential for their function. The arrangement of these structures can affect how proteins interact with other molecules and carry out their biological roles.


Alpha helices and beta-pleated sheets are examples of .?

protein secondary structures, which are common motifs found in protein folding. Alpha helices are formed by a right-handed coil of amino acids stabilized by hydrogen bonding, while beta-pleated sheets are formed by hydrogen bonding between adjacent strands of amino acids running in parallel or antiparallel orientation.
