As we’ve discussed, a peptide bond is made when amino group of one amino acid combines with the carboxylic acid group of another amino acid (releasing a water molecule in the process). The C-N bond formed in this process is called a peptide bond. Peptide bonds have a few properties that might be unexpected. a) One property is that the molecular geometries around the C and N atom in the peptide bond are generally planar with bond angles of approximately 120 degrees. Provide an explanation for why the peptide bond would have this property, using Lewis structures, VSEPR theory and/or valence bond theory as appropriate.

There are four amino acids shown in this problem: two are on this page, and two are on the following page. Only three of these amino acids are the "standard" amino acids shown in the table in the textbook. One of these is very similar to a standard amino acid, but its structure is a little bit different. Identify the three standard amino acids and give their name. Identity the non-standard amino acid. You do not have to give it a name, but you do have to (a) identify the standard amino acid to which it is most similar, and (b) describe as specifically as possible how it iş different.
