Answer #1

aspartic acid will travel fastest in a water solvent on a hydrophobic substrate as leucine, isoleucine and phenylalanine are nonpolar side chain amino acids so they have hydrophobic side chain which interact strongly with surface of hydrophobic substrate and move slowly in water solvent while aspartic acid is acidic amino acid having a acid group in side chain so interact weakly with hydrophobic substrate and hence move fastest in water solvent on a hydrophobic substrate.

A 500 amino acid protein consists of 200 hydrophobic residues. Upon folding, 150 of the hydrophobic amino acids fold and form a hydrophobic core. Determine the ∆G o for the protein at 300K, considering contributions from both the protein and the water. Assume the following: When the protein folds, each amino acid (hydrophobic and hydrophilic) forms an interaction that is 3 kJ/mol more stable thant the unfolded state. In the unfolded state, the hydrophobic amino acids contact and influence the...

In biological macromolecules like proteins, the hydrophobic residues tend to clump together in the interior of the folded structure. What is the best explanation for why this occurs? A. Hydrophobic residues bind each other, while polar residues cannot bind each other. Therefore the hydrophobic ones end up stuck to each other in the core of the protein. B. Polar residues tend to bind to water in the cytoplasm as well as to each other. The water and polar residues cannot...
