This is the mature protein shape that is the result of the many bonds made by the various R groups of the different amino acids. Hydrophobic and hydrophillic bonds, hydrogen bonding, sulfur covalent bonds and the like twist the protein into its globular shape.

Proteins with more than one polypeptide chain have what structure?
These have quaternary structure. This is the overall shape of all the chains combined. The 3D shape of one polypeptide chain is the tertiary structure.
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 tertiary is the R groups interactions that are ionic. The polypeptide chain also has disulfide bond, and hydrophobic interactions.
How can you distinguish between primary secondary tertiary and quaternary structures of proteins and can you give an example of each?
Primary structure of proteins refers to the exact sequence of the amino acids in the polypeptide chain. Secondary structure refers to the shape acquired by the backbone of the polypeptide chain when hydrogen bonds form between the carboxylic group of one amino acid and the amide group of another amino acid. there are two shapes in secondary structured proteins: Alpha Helix and Beta-pleated sheet tertiary structure refers to the shape taken up by the polypeptide chain as a result of bonds formed between the R-groups of the amino acids. three types of bonding may exist: Hydrgen bond, ionic bond and /or disulphide bonds.
How tertiary structure is stabilized?
The foldings of the tertiary structure are generally monitored by proteins called "chaperonins". These protein complexes have two rings that are stacked on top of each other like a cylinder. The complex has enough room to contain the polypeptide for folding into its 3-d shape.
How is tertiary protein structure dependent on primary protein structure?
The relationship between the primary and tertiary structure of a protein is the both have a sequence of amino acids in a polypeptide chain.orThe sequence of amino acids in a primary structure determines its three-dimensional shape ( secondary and tertiary structure)
Globular or fibrous polypeptide chains are what type of protein structure?
Tertiary structure.
The overall three-dimensional shape of a single polypeptide is called the?
It is called the tertiary structure.
Proteins with more than one polypeptide chain have what structure?
These have quaternary structure. This is the overall shape of all the chains combined. The 3D shape of one polypeptide chain is the tertiary structure.
Quaternary structure of proteins?
The quaternary structure is the overall structure of an enzyme complex. This is made of at least two separate polypeptide chains. The 3D structure of one polypeptide is known as the tertiary structure.
Hydrogen bonds between different parts of the polypeptide chain result in which level of protein structure?
Tertiary structure
A protein folded into a globular shape in having only one polypeptide chain has what structure?
tertiary
What is a tertiary protein structure exemplified by?
Hemoglobin - formed with alpha helices and/or beta sheets, but as one, contiguous polypeptide. Superoxide dismutase would be a good example of a quaternary structure protein, since it is made of more than one polypeptide chain.
What is the teritary structure of a protein?
The tertiary structure of a protein is just how a polypeptide folds up into a "glob" or a "pretzel-like" shape. Primary structure determines secondary and tertiary structure of a protein. Usually a tertiary protein is held together Disulfide bonds like those found in a Cysteine residue.
What are the forces which create the tertiary structure of a polypeptide?
Four of them are; hydrophobic and hydrophilic interactions, hydrogen bonding and disulphide bridging.
What is the level of protein structure that describes all aspects of the three-dimensional folding of a polypeptide?
Primary: Simple string of amino acids called a polypeptide. Secondary: The varied hydrogen bonding of the side chains resulting in alpha helixes and beta sheets. Tertirary: The R group bondingd; hydophobic, hydrophilic, hydrogen bonding and disulfide bonding, which results in the globular, actual protein. Quarternary: The construction of multi protein subunits from tertiary structure. Such as hemeglobin.
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.
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 tertiary is the R groups interactions that are ionic. The polypeptide chain also has disulfide bond, and hydrophobic interactions.
