What are the non covalent bonds in graphite?
Van der Waals interactions
Why could covalent bonds not be used in place of non covalent bonds to mediate most of interactions with macromolecules?
because covalent bond involve sharing pair of electrons and non covalent bond involve more dispersed variations of elctromagnetic interactions which maintain the three dimensional structure of molecule
Why small molecule - protein interactions are generally domninated by hydrophobic interactions?
An example of the protein-protein interactions is the antigen-antibody interactions. Because of the complexity of the protein molecules, the hydrophobic interactions are more dominant.
Does oil have a polar covalent bond?
No. If oil did have a polar covalent bond, that would make it hydrophilic (attracted to water) and oil is hydrophobic (repels water). All the covalent bonds in the hydrocarbon tails are non-polar covalent.
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 bonds are the last to break when an enzyme is heated 1 disulphide 2 hydrogen 3 hydrophobic interactions 4 ionic?
disulphide since it is covalent

Is a quaternary structure a polypeptide sequence of amino acids?
No, the polypeptide sequence of amino acids is the primary structure of a protein. The quaternary structure of the protein is the non-covalent interactions (hydrophobic binding, van der wals forces etc..) between subunits/domains of a protein.
What are hydrophobic interactions are exhibited with?
nonpolar molecules
Is protein's primary structure formed by hydrophobic interactions?
Ni, just peptide bonding. Hydrophobic interactions do not have significance to folding until tertiary structure folding.
what two amino acids would heavy metals disrupt the non covalent interactions with?
glycine and aspartic acid
Why does the tail of the phospholipid molecule of the cell membrane has a hydrophilic head and a hydrophobic tail?
tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.

Is Hydrophobic interactions are stronger than hydrogen bond?
Hydrophobic interactions are repulsive and hydrogen bonds are attractive forces. So, not sure hydrophobic interaction is classified as a "force" but rather and "interaction". Hydrogen bonds are relatively strong forces. It's really difficult to compare hydrophobic interaction with hydrogen bond because they are sort of opposite.
