Protein is a Polymer of Amino Acids Flashcards
1
Q
How are amino acids joined together?
A
Through peptide bonds
2
Q
Is there rotation around the N-C (peptide) bond in a polypeptide?
A
No because the bond angle is fixed.
3
Q
What is the difference between amino acids and amino acid residues?
A
Amino acids are the individual subunits before polymerization. After polymerization and the N- and C-terminals have been altered, the remainders of the amino acids are called the amino acid residues.
4
Q
What is a peptide?
A
Any chain of amino acids linked to one another.
5
Q
What is a protein?
A
Usually a longer peptide which has folded into a unique 3D shape which has a defined function.
6
Q
Which terminus of the peptide is written to the left? The right?
A
N-terminus at left, C-terminus at right.
