Deamination is the removal of an amino group (-NH2) from a molecule. The end products of deamination depend on the molecule being deaminated, but generally include:

1. Ammonia (NH3): This is the primary end product of deamination. It's a toxic compound, so the body must quickly convert it to urea in the liver for excretion in urine.

2. Keto acid: The remaining molecule after the amino group is removed becomes a keto acid. This keto acid can then be used for energy production through the citric acid cycle or converted into glucose through gluconeogenesis.

3. Other products: Depending on the specific amino acid, deamination can also produce other products like:

* Alpha-ketoglutarate: From glutamate deamination

* Oxaloacetate: From aspartate deamination

* Pyruvate: From alanine deamination

Example:

Let's consider the deamination of the amino acid alanine:

* Alanine: CH3CH(NH2)COOH

* Deamination: CH3CH(NH2)COOH → CH3COCOOH + NH3

* Product: Pyruvate (CH3COCOOH) and ammonia (NH3)

Overall, the end products of deamination are ammonia, a keto acid, and possibly other specific compounds depending on the amino acid being deaminated.
