Amino acids joined together into a polypeptide chains are called residues
2
Q
What helps to form the alpha helix?
A
The H-bonding between carbonyl group “n” and the hydrogen atom of amide group of the residue “n + 4” on the same polypeptide chain.
3
Q
What gives the alpha helix the cylindrical shape and the stable alpha helix structure?
A
The hydrogen bonding between carbonyl oxygen and “n+4” carbon of the residue forming the hydrogen bond
4
Q
