dwhitmarsh : you have tyrosine miss pelled as tryosine.
mfabzak : Thanks for sharing!
smonks : i think you have histidine wrong. you are missing the hydrogen that is bound to the other nitrogen in the ring. that is what makes histidine positively charged.
jacobdino : u guys sound smart
springman10 : was up peps
mfeduck : histidine is only positively charged at a pH of below 6.00. Therefore, at physiological pH (closer to 7), it does not have an H on the double-bonded nitrogen, therefore is neutral overall
