In most cases, mutations in the core of a protein that replace a
smaller nonpolar side chain in the wild-type (e.g., Ala, Val) with
a larger nonpolar side chain (e.g., Leu, Ile, Phe, Trp) in the
mutant, result in significant destabilization and misfolding of the
mutant. What feature of the protein core explains this observation?
Why would such a mutation prevent a protein from folding
properly?

Which of the following is IMPROBABLE? WHY? A hydrogen bond between the side chains of glutamate with the side chain of serine An ionic bond with between the side chains of lysine and aspartate Hydrophobic interactions between the side chains of leucine and isoleucine Salt bridges between alanine and histidine A backbone hydrogen bond between C=O on one amino acid with the N-H of another amino acid 4 residues away.

True or false? True False Phenylalanine's side chain is more polar than tryptophan's or tyrosine's side chains. True False Almost all peptide bonds in proteins are in the trans configuration. True False In folded globular proteins, the side chains of hydrophobic amino acids are mostly buried in the interior of the protein. True False The peptides I-A-G-Y-L-S and S-L-Y-G-A-I are different molecules with different properties. True False Poly lysine will tend to form an alpha helix in solution at pH 6.8. True False Amyloidoses such as...

See the side chain of the amino acid isoleucine on page 113 of your textbook. This side chain contains three methyl groups. In a folded protein in aqueous solution, an isoleucine residue is most likely to be found A. On the surface of the protein, forming hydrogen bonds with water molecules B. On the surface of the protein, paired with another amino acid in an ionic bond C. In the interior of the protein, hydrogen bonded to other groups D....
