Hope you are well. I have some questions regarding ochem
At ph=9.5, tyrosine exists with a net charge of -1. The answer explanation is that the amino terminal and side chain are neutral. While the carboxyl is negative. I understand the negative thing, but why the neutral. Why is it that some amino acid is neutral (though still depronated or protonated), while others carry charge? On the exam, how do I know if it is neutral or charged?
Thank you,
swift
