To classify serine as (1) ketogenic, (2) glucogenic, or (3) both ketogenic and glucogenic. 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. 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. There are 20 standard amino acids. Each amino acid has a different carbon skeleton and has a different degradation pathway for its 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 α-ketoglutarate , succinyl CoA , fumarate, oxaloacetate, pyruvate, acetyl CoA and acetoacetyl CoA .

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
