Ammonia can be produced by the break-down of amino acids, or by the gut bacteria in humans. If the level of ammonia in the blood becomes too high, then it becomes toxic to the brain. The urea cycle ...

Urea cycle disorders are congenital diseases that are caused by a dysfunctional urea cycle. The genetics and biochemistry of these disorders have been extensively studied. They are the result of a ...

Diatoms are the main component of phytoplankton and thus form the basis of the marine food chain. Because they carry out photosynthesis with their chloroplasts, they account for a large proportion of ...

The combination of intravenous sodium phenylacetate and sodium benzoate has been shown to lower plasma ammonium levels and improve survival in small cohorts of patients with historically lethal ...

Scientists have discovered that marine diatoms, tiny phytoplankton abundant in the sea, have an animal-like urea cycle, and that this cycle enables the diatoms to efficiently use carbon and nitrogen ...

The number of elderly suffering from Alzheimer’s Disease has been rapidly rising over the past decades. For a long time, scientists believed that misfolded aggregates of amyloid-beta protein ...

This release is available in German. The urea cycle is a metabolic pathway used in mammals to incorporate excess nitrogen into urea and remove it from the body. However, it appears to play a far more ...
