I don't get the question, but it won't work if its hydrogen bonds are broken.

Some regions of a polypeptide may coil or fold back on themselves?

Yes, certain regions of a polypeptide chain can coil or fold back on themselves due to interactions between amino acids within the chain. These interactions, such as hydrogen bonding and hydrophobic interactions, help stabilize the folded structure of the protein, ultimately determining its function.


What bonds can be affected by pH and temperature changes?

Ionic bonds are affected by pH changes because they depend on charged ions. Hydrogen bonds can be influenced by both pH and temperature changes, as the interactions between molecules can vary based on these factors. Additionally, disulfide bonds in proteins can be affected by both pH and temperature changes, leading to denaturation of the protein structure.


The final three dimentional shape of a protein is?

The final three-dimensional shape of a protein is known as its tertiary structure. This structure is determined by the interactions between amino acid side chains, such as hydrogen bonding, disulfide bonds, hydrophobic interactions, and electrostatic interactions. The tertiary structure is crucial for the protein's function and determines how it interacts with other molecules.


What are four levels of protein structer and the basis of each?

Primary structure: This is the linear sequence of amino acids in a protein, determined by the genetic code. Secondary structure: This refers to the local folded structures within a protein, such as alpha helices and beta sheets, stabilized by hydrogen bonding between amino acids. Tertiary structure: This is the three-dimensional arrangement of the entire protein molecule, driven by interactions between side chains of amino acids, including disulfide bonds, hydrogen bonds, and hydrophobic interactions. Quaternary structure: This level of protein structure refers to the arrangement of multiple protein subunits (if present) and their interactions to form a functional protein complex.


What helps maintain shape of protein?

The shape of a protein is maintained primarily by noncovalent interactions such as hydrogen bonds, van der Waals forces, and hydrophobic interactions between amino acid residues in the protein's structure. Additionally, disulfide bonds formed between cysteine residues can contribute to stabilizing the protein's shape. Any changes in these interactions can lead to alterations in the protein's structure and function.

What are the forces which create the tertiary structure of a polypeptide?

The tertiary structure of a polypeptide is primarily determined by interactions between the R-groups of amino acids in the protein. These interactions include hydrogen bonding, disulfide bonds, hydrophobic interactions, and electrostatic interactions. The overall folding of the polypeptide chain into its tertiary structure is crucial for the protein's function.


What level of structure in proteins is held together by intermolecular R group interactions?

Tertiary structure in proteins is held together by intermolecular R group interactions, including hydrogen bonding, hydrophobic interactions, ionic interactions, and disulfide bonds. These interactions help stabilize the folding of the protein into its unique three-dimensional shape.


What bonds are present in each of the four different levels of protein structure?

Primary- Covalent bonds Secondary- Hydrogen bonds Tertiary- Hydrophobic interactions - Disulphide bonds/bridges - Hydrogen bonding Quaternary- (Same as Tertiary)


What structural level of a protein most affected by a disruption in hydrogen bonding?

The structural level of a protein is most affected by disruption would be the secondary structure. It is within the secondary structure where the folding and coiling of the protein is stabilized by hydrogen bonds.


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.


What is a hydrogen bond donor and how does it contribute to molecular interactions?

A hydrogen bond donor is a molecule or atom that can donate a hydrogen atom to form a hydrogen bond with another molecule or atom. This contributes to molecular interactions by creating a weak attraction between the hydrogen bond donor and acceptor, which can influence the structure and properties of molecules.


What five forces are responsible for stabilisation of protein tertiary structure?

There's a few but some of them are:- hydrogen bonding hydrophobic interactions electrostatic interactions van der waals forces disulphide forces salt bridges.

These interactions, such as hydrogen bonding and hydrophobic interactions, help stabilize the folded structure of the protein, ultimately determining its function.


What is the role of a molecule as a hydrogen bond acceptor and donor in chemical interactions?

In chemical interactions, a molecule acts as a hydrogen bond acceptor by accepting a hydrogen atom from another molecule, and as a donor by donating a hydrogen atom to another molecule. This allows for the formation of hydrogen bonds, which are important for stabilizing the structure of molecules and facilitating various chemical reactions.


Is hydrogen affected by the sun?

no hydrogen is not affected by the sun because hydrogen can be combined with helium it creates a fuel source but it is not affected by hydrogen by it self so no hydrogen is not affected by the sun

What type of bonds are there for the four different type of protein structure?

The four different types of protein structures are determined by the interactions between amino acid residues in the polypeptide chain. These structures are held together by different types of bonds: primary structure by peptide bonds, secondary structure by hydrogen bonds, tertiary structure by disulfide bonds, hydrogen bonds, ionic bonds, and hydrophobic interactions, and quaternary structure by the same bonds as tertiary structure.
