The proper assimilation of Se into foods depends on their bioavailability, bioaccessibility, and/or bioactivity of a given Se compound. SeM is the main Se species found in bread supplemented either by adding selenite directly to the dough or by using lab-grown, Se-enriched yeast. The highly bi...
The meaning of HYDROGEN CYANIDE is a poisonous usually gaseous compound HCN that has the odor of bitter almonds.
The term "hydride" suggests that the H atom has acquired a negative or anionic character, denoted H−, and is used when hydrogen forms a compound with a more electropositive element. The existence of the hydride anion, suggested by Gilbert N. Lewis in 1916 for group 1 and 2 salt-like...
Hydrogen chloride available in the manufacture of organic silanes as a by-product containing a hydrolyzable organic silicon compound by removing the silicon compound therefrom through adsorption using activated carbon. The carbon is gradually deactivated as it is repeatedly subject to adsorption and ...

or methane. Mixtures of Hydrogen, carbon monoxide, or methane and oxygen difluoride are exploded when a spark is discharged, [Mellor 2, Supp. 1:192(1956)]. An explosion occurred upon heating 1'-pentol and 1''-pentol under Hydrogen pressure. Hydrogen appears that this acetylenic compound ...
This process, considered as a ‘trick’ or ‘short cut’ to avoid the high energy requirements of ambient temperature water oxidation, does not come free of charge (as often stated). The energy saving obtained using such compounds is paid for by the chemical energy contained in the compound ...
