Understand the Problem
The question is asking for information about amino acids that contain side chains which can accept or donate protons, thus becoming charged under certain pH conditions.
Answer
arginine, tyrosine, lysine, cysteine, histidine, glutamate, and aspartate
The final answer is arginine, tyrosine, lysine, cysteine, histidine, glutamate, and aspartate.
Answer for screen readers
The final answer is arginine, tyrosine, lysine, cysteine, histidine, glutamate, and aspartate.
More Information
These amino acids contain side chains that can gain or lose protons, thus altering their charge depending on the pH of their environment.
Tips
A common mistake is to incorrectly include or exclude certain amino acids. For example, serine and threonine do not have ionizable side chains.
