Which mnemonic is used to remember the chemical nature of acidic amino acids?

• A. Polar AAʻs
• B. Santas Team Crafts New Quilts Yearly
• C. Digestive Enzymes
• D. Salty Banana

Answer: (C)

The mnemonic that best helps with remembering the chemical nature of acidic amino acids is related to the phrase "Salty Banana." This phrase is particularly effective because it highlights the two acidic amino acids in the standard twenty: aspartic acid and glutamic acid. The "Salty" component can be associated with the negatively charged nature of these amino acids at physiological pH, due to their carboxyl groups that lose protons to become negatively charged, resembling something that could be associated with salt. The imagery of a "Banana" may serve as a cue to help recall that these amino acids are distinct within the larger group of amino acids because of their acid-base properties. Thus, this catchy phrase ensures both the identification of the acidic nature and the specific amino acids that fall under this classification. In contrast, other options do not specifically relate to the acidic amino acids. For instance, "Polar AA's" pertains to polar amino acids but does not convey the acidic nature. "Santas Team Crafts New Quilts Yearly" is a mnemonic for remembering the essential amino acids, and "Digestive Enzymes" does not connect directly with the chemistry of amino acids. Therefore, "Salty Banana" stands out as the appropriate choice
