Answer:
In the α helix structure, there is a hydrogen bonding between oxygen atom in a carbonyl of one amino acid and the hydrogen atom of the amino group that is situated four residues farther along the polypeptide chain
Explanation:
The common secondary structure of protein are: <em>α helix and β pleated sheet</em>
<em>α helix </em>is a rod like structure.<em> </em>It is a<em> right handed coil </em>of amino acid residue on a polypeptide chain, which may be 4 units or 40 units long. The coil is held together by hydrogen bond between oxygen atom in a carbonyl of one amino acid and the hydrogen atom of the amino group that is situated four residues farther along the polypeptide chain. This means that every complete turn of the helix is only 3.6 residues.
Bacteria protects the cell in your intestine and helps us absorb fatty acids. It is harmful because when you have contact with it, the bacteria can reproduce in your body, damaging it and making you sick.
