Are ionic bonds responsible for the primary structure of a protein?
Primary structure of a protein represents the sequence of the amino acids of that particular protein. The amino acids are bonded together by a bond called 'peptide bond'. The peptide bond is formed by carbonyl group of an amino acid with nitrogen group of the adjacent amino acid. Only this peptide bond is responsible for the formation of primary structure of protein. Hence the ionic bonds are not involved in the primary structures of protein.
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 type of structure does an ionic bond have?
acrystal structure
Why is the primary structure of a protein unaffected by heating?
Primary structure is a sequence of amino acid joined covalently unlike hydrogen/ ionic bond, which is easily affected by heat, in 2' 3' 4' structures.
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.

Which bond that stabalizes a proteins tertiary structure is the strongest?
Disulfide
Which protein bond is the strongest?
hydrogen bonds
How does low pH affect secondary and tertiary protein structures?
A pH that is too acidic or basic for the protein will denature it - the bonds that connect the amino acids to each other for "folding" will break and the tertiary structure is no longer the correct structure for that protein.
What bond is involved in graphite's crystal structure?
seeing how it has a CRYSTAL STRUCTURE I would say ionic bond.
What are the different levels of protein structure and explain why tertiary structure must be maintained for protein function?
Primary = The polypeptide chain.Secondary = Hydrogen bonding of the bases form alpha helix and beta sheets.Tertiary = The R groups bond with each other ( hydrophobic, hydrophyllic, salt bridges, hydrogen bonding ) and the final form of the protein is this construction, so this form must be maintained so that the protein maintains function.Quaternary = The building of structure from more than two protein ( tertiary ) subunits. Hemoglobin, for example.
How is a hydrogen bond used in making a protein?
The bases of the various amino acids are hydrogen bonded in the secondary structure of protein synthesis. Alpha helices and beta sheets are formed. This is the step before the various R groups start bonding and folding the protein into a globular shape in the tertiary structure.

Bond stabilizes protein folded 3D structure and DNA double helix 3D structure?
non polar bond
