@learnankihub Could you share rationale for 402528?
Weird, I thought I got that one.
In this case, it’s asking to identify which of a selection of amino acids is most likely to be charged at physiological pH. Simply requires knowing that aspartate is an polar/charged amino acid. Simple enough recognition question.
You can disregard the above, I just saw the other suggestion for QID 402528 with this note
