Answer :
Amino acids join by forming (1) peptide bonds. Water is released.
The chains of amino acids vary according to their (2) side chains, which each have differing makeup.
These chains determine the protein’s structure and they fold to create a unique (3) third-dimensional shape.
Explanation :
Amino acid : The amino acids are the building blocks of protein. Amino acids are the compound which consist both amine and carboxylic
groups along with the side chains. In the protein, many amino acids are linked by the peptide bonds.
Th peptide bonds are formed by the combining of amino group of one amino acid to the carboxylic group of another amino acid by releasing of water.
Some examples of amino acids are glycine, lysine, alanine, etc.

In the image 'R' can be contained by different groups like hydrogen, methyl, phenyl, etc
This question is describing two chemical equations whereby the concentration of ammonia has to be determined. The first reaction is between 25.00 mL of ammonia and 50.00 mL of 0.100-M HCl whose excess was neutralized with 21.50 mL of 0.050-M Na₂CO₃ and thus, the concentration ammonia in the cloudy solution was determined as 0.114 M.
First of all we need to go over the titration of the excess HCl with Na₂CO₃ by writing the chemical equation it takes place when they react:
Whereas the mole ratio of HCl to Na₂CO₃ is 2:1 and the volume of the HCl leftover is determined as follows:
Next, we infer that the consumed volume of HCl by the ammonia solution was:
Then, we write the chemical equation that takes place between ammonia and HCl:
Whereas the mole ratio is now 1:1, which means that the concentration of ammonia was:
