Is insulin a quaternary or tertiary structure?
Insulin has a tertiary structure which is folded into a spherical shape. An insulin molecule comprises two chains of amino acids held together by disulfide bonds. This is the active state of the hormone.
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)
Which level of protein structure may be stabilized by covalent bonds?
Primary, tertiary and quaternary levels of protein 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.
Is collagen a secondary or tertiary structure?
With most proteins, it has a secondary and tertiary structure.
Which bond that stabalizes a proteins tertiary structure is the strongest?
Disulfide
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.

Which level of protein structure may be stabilized by covalent bonds?
Primary, tertiary and quaternary levels of protein structure.
What bonds do Tertiary and quaternary structure of proteins involve?
Several, and they are mostly the same as tertiary structure. Hydrogen bonding, London dispersion/Van der Waal's forces, dipole moments, disulfide bonds, and occasionally (such as in hemoglobin), ionic bonding.
Disulfide bridges are found in what level of protein confirmation?
Tertiary
How does the shape of a protein change as it goes from primary to quaternary?
The primary structure of a protein is the unique sequence of amino acids. There are 20 possible amino acids, and the primary structure consists of a string of amino acids held together by peptide bonds. The secondary structure occurs when the amino acid chain becomes coiled or folded in alpha helix or beta pleated sheets. The protein develops its three-dimensional shape in the tertiary structure. Van der Waals interactions, disulfide bonds, hydrophobic interactions, and ionic bonding all impact the tertiary structure. Finally, the quaternary structure is made up of more than one polypeptide chain (a polypeptide chain is the string of amino acids described in the primary structure). Hope this helps!
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.
Disulfide bonds may be part of?
Disulfide bonds between cysteine amino acids in a peptide chain are critically in stabilizing preferred secondary and tertiary structures. Many enzyme activities rely on specific shapes that are stabilized by these disulfide bonds.
What are some important factors in enzyme structure?
Enzymes are almost all proteins. They are often globular proteins. We can describe them in terms of their primary, secondary, tertiary and quaternary structure. They are long chains of amino acid units held together by peptide bonds, looped and folded into secondary and tertiary structures by disulfide bonds, hydrophobic interactions, and salt bridges.
