How do you draw a formation of a peptide bond with two amino acids in structural formation?

a peptide bond is formed when a carboxylic acid group and amine group condense.
lets take glycine for example. H2N-CH2-COOH
the carboxylic acid group COOH loses the OH group and the amine group of the second amino acid loses one H. these lost groups form the water molecule, hence the term condensation reaction.
H2N-CH2-CO-HN-CH-COOH + H2O
note that the peptide bond is -CONH- where the atom O is doublebonded to the C and the H is single bonded to the N.

.............O
NH2-CH-C-N-CH-COOH
.........R1.......R2
This is a little rough - I added some periods just as space holders - remove them in your structure. You also need to add a double bond between the C and O (C=O) on top and a single bond between each CH and R below. The C double bond O Nitrogen is the peptide bond. The R groups will be different depending on the actual amino acids side chains.

Wrong! it's amino

You can find an excellent diagram of this reaction here
