A debate has been raging about the look and style of Crocs shoes since they were first introduced in 2002, but now some schools are banning them as a safety hazard. At Bessemer City High School in ...
Nitroso compounds react with primary amines in acidic environments to form nitrosamines, which human metabolism converts to mutagenic diazo compounds. Small amounts of nitro and nitroso compounds form during meat curing ; the toxicity of these compounds preserves the meat against bacterial infection .
Ethylenediamine (abbreviated as en when a ligand) is the organic compound with the formula C 2 H 4 (NH 2) 2.This colorless liquid with an ammonia-like odor is a basic amine.It is a widely used building block in chemical synthesis, with approximately 500,000 tonnes produced in 1998. [6]

Trimethylamine is a full agonist of human TAAR5, [13] [14] [15] a trace amine-associated receptor that is expressed in the olfactory epithelium and functions as an olfactory receptor for tertiary amines. [15] [16] One or more additional odorant receptors appear to be involved in trimethylamine olfaction in humans as well. [16]
