Concept explainers
Interpretation: To identify the correct pairing of standard amino acid carbon skeleton degradation product and amino acid genicity.
Concept introduction: Genicity of an amino acid is defined as whether the carbon skeleton degradation product of an amino acid can produce glucose or
There are 20 standard amino acids and each has a different carbon skeleton. An amino acid is known as a glucogenic amino acid if its carbon-containing degradation product can be used to produce glucose. An amino acid is known as a ketogenic amino acid if its carbon-containing degradation product can be used to produce ketone bodies.
The degradation pathways for different amino acids merge in between and result in the formation of only 7 products. The 7 products are
Fates of carbon skeletons of different amino acids are as follows:
