adding amino acids to a molecule??

Post by biochem1278 » Sat Oct 02, 2010 1:23 pm

I am trying to figure out how to add three amino acids to a molecule.

The molecule has a carboxylic acid, amino group, a N+ atom and an OH group.

I know I can add an amino acid to the carboxylic acid and the amino group. However, I'm not sure if I can add the third one to the OH group. I imagine I could add one to the the N+ atom (however, its embedded within a benzene ring).


Does anyone know if you can add an amino to a lone OH group (not in a carboxylic acid) or to a N+ atom?

I have not found any examples of an amino being added to anything other than a carboxylic acid so this is what confuses me.

1) if there is N, then it is NOT benzene!

2) amino acid contains amino and carboxylic groups (or some others) and that shows it's reactivity. Simply, it will react as any carboxylic acid or amine, e.g. with hydroxyl forming ester.
However, what exactly is your purpose?

Cis or trans? That's what matters.
