Which pair(s) of amino acids cannot have hydrophobic interactions:a)Le...
Explanation:
Hydrophobic interactions refer to the tendency of nonpolar molecules to cluster together in an aqueous solution. Amino acids can be classified as hydrophobic or hydrophilic based on their polarity.
A) Leucine and alanine:
- Leucine is a hydrophobic amino acid with a nonpolar side chain.
- Alanine is also a hydrophobic amino acid with a nonpolar side chain.
- Therefore, these two amino acids can have hydrophobic interactions.
B) Arginine and glutamic acid:
- Arginine is a hydrophilic amino acid with a positively charged side chain.
- Glutamic acid is a hydrophilic amino acid with a negatively charged side chain.
- Since both amino acids are hydrophilic, they cannot have hydrophobic interactions.
C) Glycine and asparagine:
- Glycine is a hydrophilic amino acid with a small, nonpolar side chain.
- Asparagine is a hydrophilic amino acid with a polar side chain.
- Since both amino acids are hydrophilic, they cannot have hydrophobic interactions.
D) Glutamic acid and serine:
- Glutamic acid is a hydrophilic amino acid with a negatively charged side chain.
- Serine is a hydrophilic amino acid with a polar side chain.
- Since both amino acids are hydrophilic, they cannot have hydrophobic interactions.
Therefore, the correct answer is options B, C, and D.
