Which mnemonic refers to polar uncharged amino acids?

• A. Santas Team Crafts New Quilts Yearly
• B. Her Red Dress Kills (at) Events
• C. Good Spaghetti Always Comes (with) Tomatos
• D. Acidic AAʻs

Answer: (C)

The correct mnemonic for remembering polar uncharged amino acids is "Santas Team Crafts New Quilts Yearly." This phrase includes the initials of the amino acids that are categorized as polar and uncharged: Serine (S), Threonine (T), Cysteine (C), Asparagine (N), Glutamine (Q), and Tyrosine (Y). Each word in the mnemonic corresponds to the first letter of an amino acid in this group, helping students recall them more easily.

The other options do not accurately represent the polar uncharged amino acids. For example, "Her Red Dress Kills (at) Events" refers to the basic amino acids, while "Good Spaghetti Always Comes (with) Tomatos" is a common mnemonic for nonpolar amino acids. "Acidic AAʻs" indicates acidic amino acids, which are a different set altogether, including aspartic acid and glutamic acid. Thus, the clarity of the correct mnemonic in linking directly to polar uncharged amino acids is what makes it the most suitable choice.
