Amino acids.
Amino acids are the molecules that bond together to produce a protein. Proteins are made up of chains of amino acids that are linked together through peptide bonds. The sequence of amino acids in a protein determines its unique structure and function.
Two single chains bond together. The bonded chains twist together to form a double helix.
The type of bond responsible for linking two water molecules together is a hydrogen bond.
peptide bond
This is an intermolecular bond.
The bond in water is covalent.
Yes, that's how molecules are formed.
molecules
Molecules.
No, the bond is a polar covalent bond.
PrecipitaionLets take protein in water as a solution as an example. Protein consists of hydrophobic amino acids and hydrophilic amino acids. Hydrophobic amino acids are usually seen in the protein core and hydrophilic aminoacids forms hydrogen bond with water molecules. When an organic solvent, or salt is added to the solution water molecules which are in hydrogen bond with the hydrophilic amino acids break the bond and binds with the salt or solvent. Thus protein protein interaction becomes stronger than protein -water interaction. So due to partial dipole interaction and electrostatic force of attraction protein molecules aggregate and precipitate.FlocculationConsider a solution of proteins. If the solution is agitated continuously the protein molecules come together. If the agitation is that stronger effect to overcome the electrostatic force of repulsion between the protein molecules, they will cling together and forms floc. Another method is adding chemicals called flocculants. By adding floculants the electrostatic repulsion between the protein molecules can be reduced and this will lead to attraction of protein molecules and formation of floc.
