If you were to have a mythical amino acid based on glutamic acid, but one in which the hydrogen that is attached to the v-carbon were roplaced by another amino group, what would be the predominant form of this amino acid at pH12 if the pKa value were 10 for the unique amino group? (Select all that apply.) The amino acid carries a negative 2 charge. Both of the amino groups are deprotonated. The amino acid carries a negative 4 charge. Both of the carboxyl groups are deprotonated. The amino groups are in the form -NH
