Deamination

Deamination of amino acids results in the production of ammonia (NH3).
Ammonia is an extremely toxic base and its accumulation in the body would quickly be fatal.

VSP repair
"Very short patch" DNA repair. A DNA repair mechanism that corrects G-T mismatches arising from deamination of 5-methyl cytosine in enteric bacteria. A short DNA fragment including the mismatch is excised and resynthesized.

When no glucose or glycogen is available, amino acids are converted into glucose in the liver. The process of deamination removes the amino groups from amino acids. Urea is formed and passed through the blood to the kidney for export from the body.
