Answer: No hydrogen bond cannot occur in this alpha helix structure.
Explanation: For hydrogen bond to form, the electronegativity difference should be more than 1.7. carbon has an electronegativity of 2.5 whereas hydrogen has 2.1 so their electronegativity difference is 0.3. So in this alpha helix structure cannot occur.
Umm where is the question Is this a question ?
<span>The answer is iron. Iron has an atomic number of 26. This means than iron has 26 protons in it's nucleus. However, not all iron atoms have the same number of neutrons.
