what group does NH2 of amino acid beling to?
Homework Answers
NH2 of amino acid belong to primary amiine. It is the primary amino because one of the hydrogen atom of amine group is replaced by alkyl or aromatic group.

The carboxylate group on the amino acid valine is activated in an early step in the biosynthesis of the antibiotic penicillin. Predict the product of this reaction and draw the likely intermediate of the phosphate group transfer reaction. Feel free to use "R" for the adenosine (nucleic acid and sugar) portion of ATP in your structures. ATP PP H₃N co valine NH2 Intermediate o-P-O-P-O-P- 0 0 ATP HOH OR

b: Before neutralization the solution (is
acidic/is basic) and the (protonated amino group/deprotonated amino
group/protonated ester group) makes benzocaine soluble in the
aqueous solution. When the sodium carbonate is added, the (amino
group is deprotonated/amino group is protonated/ester group is
deprotonated) and the neutral benzocaine produced has a (low
solubility in water/high solubility in water/higher density than
water).
The local anesthetic, benzocaine, can be prepared by the direct esterification of p-aminobenzoic acid with ethanol, using sulfuric acid as the catalyst....
