Which of the following pair of amino acids develops hydrophobic interactions?

Question

Quizplus · Accepted Answer

Hydrophobic interactions occur between non-polar amino acids, like those found in leucine and phenylalanine, and is essential for the formation of protein structures such as alpha helices and beta sheets. Alanine is non-polar, but glutamic acid has a negatively charged side chain and is thus hydrophilic. Aspartic acid has a negatively charged side chain, while lysine has a positively charged one, making it hydrophilic. Serine has a polar side chain and thus, is also hydrophilic, whereas tyrosine has a polar side chain but also has a benzene ring, which makes it partially hydrophobic.
