a consequence of the lumen-positive transepithelial voltage of the MTAL. NH4+absorption is regulated by the acid-base status. Indeed, the ability of the MTAL that has been isolated and perfused in vitro to absorb total ammonia is increased during chronic metabolicacidosis(CMA).36The Na+,K+(...
In chemistry, a covalent bond is a chemical bond in which the outer shell electrons of the constituent atoms are shared between them when the molecule is formed. One example of a common molecule that has covalently bonded atoms is water....
Our knowledge of guanidine degradation by microorganisms is also still in its infancy, but recent research has revealed two degradation pathways for guanidine that are used by bacteria to not only detoxify guanidine but also to use it as a nitrogen source and, ultimately, to produce three molecule...
The results showed that ammonia is a rather expensive fuel compared to LNG and DME or methanol. Whereas ammonia itself does not contain CO2, the ammonia production process is energy intensive – energy mainly converted from fossil fuels –which is also important in any sort of comprehensive ...
In a recent global analysis of satellite-derived atmospheric NH3 data, a hotspot was observed in the vicinity of Lake Natron, Tanzania. The lake is in the centre of an endorheic (limited drainage) basin and has shallow, saline-alkaline waters. Its remote

So why is ammonia a gas and room temperature, while water and hydrogen fluoride are liquids? ...Ammonia has three hydrogen atoms, but only one lone pair of electrons. This time, you will have insufficient lone pairs to allow for the majority of ammonia molecules to hydrogen bond at a part...
But-2-ene Propan-2-ol Answer and Explanation: One way to predict 3D structure of molecules easily is by making sense of their Lewis structures, especially by paying attention to their lone electron pairs position. The general rule of thumb is that the 3D structure ...
It can be used as an alternative to phe-free amino acid mixtures as a ‘natural’ source of supplementary amino acids allowing a decrease in artificial amino acid products. As an intact protein it is generally perceived to be more palatable, however it does contain small amounts of phe ...
Electrochemical nitrate reduction to ammonia is a promising alternative strategy to the traditional Haber-Bosch process but suffers from a low Faradaic efficiency and limited ammonia yield due to the sluggish multi-electron/proton-involved steps. Herein,
