a)
Interpretation:
To identify the amino acid that is a catabolic precursor of the given α-keto acids:
Answer to Problem 17VC
Explanation of Solution
Catabolism of proteins occurs by a discrimination of α – amino acids according to the following reaction:
The retro symmetric strategy is used to derive synthons and starting materials.
b)
Interpretation:
To identify the amino acid that is a catabolic precursor of the given α-keto acids:
Answer to Problem 17VC
The corresponding α amino acid precursor is respectively:
Explanation of Solution
Catabolism of proteins occurs by a discrimination of α – amino acids according to the following reaction:
Thus, the α – keto acid derives its structure from its precursor parent amino acid by replacing the segment by .
This proves the above assigned structures for the α – amino acids.
The retro symmetric strategy is used to derive synthons and starting materials.

- O Macmillan Learning Chemistry: Fundamentals and Principles Davidson presented by Macmillan Learning Poly(ethylene terephthalate), known as PET or industrially as Dacron, is a polyester synthesized through a condensation reaction between two bifunctional monomers. The monomers, ethylene glycol and terepthalic acid, are given. Add bonds and remove atoms as necessary to show the structure of a two repeat unit portion of a longer polymer chain of PET. You may need to zoom out to see the complete structure of all four monomer units.
