Once <u>hydrogen</u> bonds form between every fourth amino acid in a polypeptide chain, the chain begins to twist into the <u>secondary</u> structure known as a(n) <u>alpha helix</u>.
<h3>
What is Amino Acid ? </h3>
Amino acids are organic compound. Amino acids contains amine and carboxyl functional group. Amino acids is the building block of life these are the molecules that combine to form proteins.
<h3>What is Polypeptide Chain ? </h3>
A unique sequence of amino acids joined by peptide bonds is called polypeptide.
Thus from the above conclusion we can say that Once <u>hydrogen</u> bonds form between every fourth amino acid in a polypeptide chain, the chain begins to twist into the <u>secondary</u> structure known as a(n) <u>alpha helix</u>.

Answer:
It changed from unsaturated to saturated solution
Explanation:
Before adding the spatula tip full amount, the solution was unsaturated, but as soon as the spatula tip full amount was added and couldn't dissolve, it became unsaturated because it could not dissolve any more solute having already dissolved it maximum number of solute
Answer:
0.1105 moles per 130 ml
Explanation:
For 1 L (1000) of solution, no of moles are = 0.85
For 1 ml of solution, no of moles are = 0.85/1000 moles
For 130 ml of solution, no of moles are= 0.85/1000 x 130
= 0.1105 moles per 130 ml
