Answer:
Secondary structure
Explanation:
Stricture of proteins can be categories into 4
Primary structure, secondary structure, tertiary structure and quaternary structure.
Primary structure are polypeptide chains. The polypeptide chains are formed by amino acids held together by peptide bonds.
Secondary structure refers to the folding of polypeptides chains. Two most common secondary structures are alpha helix and beta pleated structure. These folding occurs because of hydrogen bonding between the oxygen of the carbonyl of one amino acid and the hydrogen of another amino acid.
Therefore, hydrogen bonding is crucial for secondary structure of the protein.
Conjugate base of Propanoic acid (
is propanoate where -COOH group gets converted to -CO
. The structure of conjugate base of Propanoic acid is shown in the diagram.
The 
above which 90% of the compound will be in this conjugate base form can be determined using Henderson's equation as propanoic acid is weak acid and it can form buffer solution on reaction with strong base.
= 
+ log![\frac{[Conjugate base]}{[acid]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BConjugate%20base%5D%7D%7B%5Bacid%5D%7D)
=4.9+log
=5.85
As 90% conjugate base is present, so propanoic acid present 10%.
