What would happen if we placed an oligopeptide in a nonpolar solvent?
What would happen if we placed an oligopeptide in a polar solvent?
Homework Answers
The chemical and physical properties of peptides are dictated by their amino acid composition. Thus if an oligopeptide which is composed of hydrophilic or polar amino acids is placed in a non-polar solvent will not be soluble in it whereas an oligopeptide solely composed of hydrophobic or non-polar amino acids it will get dissolve in the non-polar solvent.
hydrophobic amino acids are-phenylalanine, valine, tryptophan, etc. and polar amino acids are serine (Ser), threonine (Thr), cysteine (Cys), asparagine (Asn), glutamine (Gln),etc.

Ok, so what would happen if you are working with TLC and have a polar stationary phase (silica) and a mobile phase ( polar eluting solution) and you spot a nonpolar compound? Would the Rf values be greater than in a nonpolar mobile phase? I know in general if you are using TLC with polar silica and spot a nonpolar compound the nonpolar compound travels further (higher Rf values) because its chemical structure is different than the stationary phase compared...

What solvent would be best to carry out the substitution of the benzyl iodide shown below and why? H2N solvent at 70 °C 1.0 equivalents Methanol, because this reaction performs best with a polar protic solvent to solvate charged intermediates. DMSO, because this reaction performs best with a polar aprotic solvent which will dissolve the nucleophile without hydrogen bonding. O Hexanes, because this reaction performs best with a nonpolar solvent to...

what is the strongest type of intermolecular force between solute and solvent in each solution? a.) Cu (s) in Ag (s) b.) CH3CH3 (g) in CH3CH2CH2NH2 (l) c.) CH3Cl (g) in CH3OCH3 (g) My guess would be: a.) they are 2 different metals that are monotomic ions so...ionic bonding? b.) the first is nonpolar? and second is polar? so....dipole induced dipole? or is the second nonpolar? C.) H-bonding with the O and H? or would it be dipole -dipole because...

Dimethyl sulfoxide is an important polar aprotic solvent that can dissolve both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water. Because it penetrates the skin very readily, it is sometimes used as a vehicle for topical application of pharmaceuticals. Draw the structure of dimethyl sulfoxide. Include any nonbonding electrons on sulfur, and minimize formal charges by allowing sulfur to expand its octet.
