nitrogen group

Part B usually has a basic nitrogen group.

When exposed to the ultraviolet rays of sunlight, many explosive compounds containing nitrogen groups rapidly decompose, affecting their stability.

The methyl group on the alpha carbon (the first carbon before the nitrogen group), also makes this compound a member of the amphetamine family.

The Halogenated nitrogen group X:halogen (for example NI and RNCl)

This interaction redistributes the positive charge and leads to the deprotonation of one nitrogen group, which can then make a nucleophilic attack on the methyl group of SAM.

The four nitrogen groups may make it soluble in acid, say HCL, and it could be fractionally precipitated by adding base, e.g. NaOH or ammonia.

Additionally, electrostatic interactions may form between the positively charged tertiary nitrogen group of vicriviroc and the hydrophilic region provided by E238 residue on TM7 of CCR5.

Generally, the hydrogen bond is characterized by a proton acceptor that is a lone pair of electrons in nonmetallic atoms (most notably in the nitrogen group, and chalcogen groups).

Phosphorus (symbol P) is a multivalent nonmetal of the nitrogen group, phosphorus as a mineral is almost always present in its maximally oxidized state, as inorganic phosphate rocks.

In chemistry, a quaternary compound is a cation consisting of a central positively charged nitrogen group atom with four substituents, especially organic (alkyl and aryl) groups, discounting hydrogen atoms.

Hepatotoxicity of INH is by nitrogen group in its chemical structure, as it is metabolized in the liver and gets converted to an ammonium molecule, which causes hepatitis.

Finally, a second one-carbon unit from formyl-THF is added to the nitrogen group and the ring covalently closed to form the common purine precursor inosine monophosphate (IMP).

Unlike its nitrogen group neighbor nitrogen, which forms a stable N molecule with a nitrogen to nitrogen triple bond, phosphorus prefers a tetrahedral form P because P-P pi-bonds are high in energy.

Several attempts are being made to miniaturize, ruggedize and make MS affordable for field applications; such as an aerosol polymer that fluoresces blue under UV but is colorless when it reacts with nitrogen groups.

The structural difference between gantacurium and these two agents (cisatracurium and atracurium) - in particular, the reverse positioning of the carboxyl ester and onium nitrogen groups - absolutely ensures that gantacurium will never undergo Hofmann elimination just as is the case with mivacurium and doxacurium.

Various combinations of electron-withdrawing substitutions in the aniline ring of these drugs, have not shown higher binding to the AR receptor than compounds which have a chloro or trifluoromethyl group at the meta position (R1) and either a cyano or nitrogen group at the para position (R2).
