| 11. | It is the keto acid produced by deamination of glutamate, and is an intermediate in the Krebs cycle.
|
| 12. | A very common ?-keto acid is ?-ketoglutarate, an intermediate in the citric acid cycle.
|
| 13. | Many transamination reactions occur in tissues, catalysed by transaminases specific for a particular amino / keto acid pair.
|
| 14. | Transamination is demonstrated if the corresponding new amino acid and keto acid are formed, as revealed by paper chromatography.
|
| 15. | The branched-chain fatty acid synthesizing system uses branched-chain ?-keto acid decarboxylase ( BCKA ) enzyme.
|
| 16. | Unlike related keto acids, it is not an intermediate or metabolite associated with amino acids and its origin is unknown.
|
| 17. | The amino group is fed into the urea cycle, leaving a deaminated carbon skeleton in the form of a keto acid.
|
| 18. | If the amino group is removed from an amino acid, it leaves behind a carbon skeleton called an ?-keto acid.
|
| 19. | Several of these keto acids are intermediates in the citric acid cycle, for example the deamination of glutamate forms ?-ketoglutarate.
|
| 20. | Semicarbazide stains ?-keto acids on the TLC plate, which must then be viewed under ultraviolet light to see the results.
