Concept explainers
A
Interpretation : The naturally occurring amino acid similar to the given compound needs to be determined.
Concept Introduction : Amino acids are the organic compounds containing
B
Interpretation : The structure of the tetra peptide containing the synthetic amino acid needs to be determined.
Concept Introduction : Amino acids are the organic compounds containing amine and carboxyl functional groups. The key elements are carbon, hydrogen, and nitrogen.
C
Interpretation : The chiral carbon atoms in the synthetic amino acid needs to be determined.
Concept Introduction : When a carbon atom has the four different groups, that carbon atom is known as chiral carbon atom.
D
Interpretation : The geometrical isomers of the synthetic amino acid needs to be determined.
Concept Introduction : Geometric isomers have the same molecular formula but the arrangements of the groups are different from one another.
