To identify the incorrect statement concerning the genicity of standard amino acid degradation products. Concept introduction: Genicity of an amino acid is defined as whether the carbon skeleton degradation product of an amino acid can produce glucose or ketone bodies or not. 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.

Question

Which of following is purely Ketogenic amino acid? a. Tyrosine b. Leucine c. Phenylalanine d. Tryptophan

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
