Which amino acids are ionizable?
Understand the Problem
The question is asking for a list of amino acids that can donate or accept protons, thereby becoming positively or negatively charged depending on the pH of the environment. This relates to their side chains' functional groups which can lose or gain protons.
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 ionizable amino acids can gain or lose protons, affecting their charge based on the pH of their environment. It's important in many biochemical processes.
Tips
A common mistake is to mix up which amino acids are ionizable with those that are non-ionizable. Remember that the ionizable amino acids have side chains that can gain or lose protons.
