|Ketoglutarate is an intermediate in the TCA cycle.|

|Histidine is an essential and a glucogenic amino acid.|

|Histidine is deaminated to urocanic acid, which is converted to 4-imidazolone 5-propionate. Hydrolysis of the later gives N-formiminoglutamate (FIGlu, which donates its formimino group to tetrahydrofolate, leaving glutamate which is then converted to alpha-ketoglutarate. Alpha-ketoglutarate is an intermediate in the Kreb's Cycle. Any amino acid whose catabolism gives pyruvate or one of the intermediate of Citric Acid Cycle is glycogenic amino acid.|

|So it gives a glycogenic amino acid x-tics.|

|Histidine give alpha-ketoglutarate which can be used to produce glucose through reverse steps of glycolysis with specific enzyme.
So it is a glycogenic amino acid.

|Histidine is a glucogenic amino acid since it is converted to an intermediate alpha-ketoglutarate which is an intermediate in glucose metabolism in TCA cycle.|

|Glucogenic amino acids are those amino acids which can be converted into glucose by gluconeogenesis.|

|I agree histidine is glucogenic amino acid since it has the ability to release the intermediate (α ketoglutarate) that can be used in the glycolytic pathway in the mitochondria.|
