Plasma ammonia is the principal source of ammonia in sweat

European Journal of Applied Physiology and Occupational Physiology, 1992
Sweat contains ammonia. However, neither its source nor factors affecting its concentration in the sweat are known. The aim of this study was to examine the effect of plasma concentrations of ammonia and urea on the concentration of ammonia in the sweat. Four groups of male volunteers were examined: one control, two after ingestion of ammonium chloride,

The role of ammonia in promoting ammonia borane synthesis

Dalton Transactions, 2016
Mechanistic studies point toward added ammonia acting as a reagent while promoting the high-yielding synthesis of pure ammonia borane from sodium borohydride and ammonium salts.

IX. On the union of ammonia nitrate with ammonia

Philosophical Transactions of the Royal Society of London, 1873
1. Ammonia nitrate possesses the somewhat remarkable property of combining with large quantities of ammonia. The product is a liquid the composition of which varies with the temperature and pressure to which it is subjected. It appears from its properties to be a solution of ammonia nitrate in liquefied ammonia, analogous in every respect to an aqueous

[Effect of Free Ammonia on Ammonia Escape During an Ammonia Oxidation Process].

Huan jing ke xue= Huanjing kexue, 2017
This study used short process nitrification sludge to investigate the effect of high free ammonia (FA) on ammonia escape during ammonia oxidation. A sequencing batch reactor (SBR) was used to study the ammonia escape process under different FA concentrations.

Ammonia Inhalation

The Journal of Trauma: Injury, Infection, and Critical Care, 1985
Because of the widespread use of ammonia in industry and agriculture there is a growing opportunity for ammonia burns to occur. Two fatal cases are presented. The injury is thermal as well as chemical, to skin, eyes, airway and lungs. Prompt (5-10 seconds) irrigation of the eyes is required, and immediate treatment of airway and pulmonary injuries ...

Ammonia Transport

EcoSal Plus, 2004
This review reviews the ammonium/methylammonium transport (Amt) proteins of Escherichia coli and Salmonella enterica serovar Typhimurium. The Amt proteins and their homologs, the methylammonium/ammonium permease proteins of Saccharomyces cerevisiae , constitute a ...
