Figure 3.7 on Page 50.
It is the bond between the Carbon and the Nitrogen
The carbon is part of a Carboxyl Group
The Nitrogen is part of the Amino Acid. |

Term
| Why are peptide bonds stable? |
|
Definition
The electrons are partially shared. It is like a
"double bond" but it isnt.
It is like the octet rule. The shells are happy.

|
Term
| When writting a polypeptide, which end of a polypeptide is placed on the left and is called the N-terminus or Amino-terminus |
|
Definition

|
Term
| When writting a polypeptide, which end of a polypeptide is placed on the right hand side and is called the C-terminus or Carboxyl-terminus |
|
Definition
| The end with the free carboxyl group. |
|

|
Term
| Amino Acids in the polypeptide chain are alway number from which side? |
|
Definition
|
|
Term
| Why are amino acids in the polypeptide chain numbered from the N-Terminus side? |
|
Definition
| Because the N-Terminus is the start of the chain when protiens are synthesized in cells. |
|
|
Term
| Can a peptide bond rotate? |
|
Definition
| NO! Because it's double bond nature. |
|
|
Term
| What bonds can rotate in a polypeptide? |
|
Definition
| The single bonds on either side of the peptide bond. |
