What mnemonic can be used to recall common polar uncharged amino acids?

• A. Good Spaghetti Always Comes (with) Tomatos
• B. Her Red Dress Kills (at) Events
• C. bow Down to Alpha, Beta beat me Up
• D. Please Think Twice

Answer: (A)

To recall the common polar uncharged amino acids, the mnemonic "Good Spaghetti Always Comes (with) Tomatos" is effective because each initial letter corresponds to one of the amino acids.

In this mnemonic:

• "Good" stands for Glutamine

• "Spaghetti" stands for Serine

• "Always" stands for Asparagine

• "Comes" stands for Cysteine

• "(with)" serves as a connector

• "Tomatos" stands for Threonine

These amino acids—Glutamine, Serine, Asparagine, Cysteine, and Threonine—are all characterized as polar and uncharged, making this mnemonic particularly useful for students trying to memorize them for exams such as the MCAT. The other options do not represent the correct set of polar uncharged amino acids, as they focus on different combinations or characteristics that do not align with the amino acids specified in the question.
