Concept explainers
(a)
Interpretation: To identify the compound(s) to which leucine is
Concept introduction: Amino acids are the main building blocks of proteins. Amino acids that participate in peptide bond synthesis in proteins are known as standard amino acids.
There are 20 standard amino acids and each amino acids have different metabolic degradation pathways for their carbon skeleton. The degradation pathways for different amino acids merge in between and result in the formation of only 7 products. The 7 products are
(b)
Interpretation: To identify the compound(s) to which isoleucine is metabolized.
