It was found that oxirane ring undergoes nucleophilic attack by the primary amine
groups of chitosan and the degree of crosslinking increased with increase in curing time, curing temperature and concentration of chitosan.
The AO family encompasses FAD-dependent enzymes (essentially MAO and polyamine oxidase) and copper-containing amine oxidases, having for predominant members the products of the genes AOC1, 2, and 3, the latter being named semicarbazide-sensitive amine oxidase (SSAO) or primary amine
oxidase and also currently known as vascular adhesion protein-1 (SSAO/VAP-1) [5,6].
OPA assay: When o-Phthlaldehyde (OPA) bonds to primary amine
groups within an aqueous solution it gains the ability to fluoresce.
DKP is formed through the intramolecular reaction of the primary amine
with the methyl ester group of aspartame.
The antiepileptic drug (AED) vigabatrin, a [gamma]-vinyl analog of the neurotransmitter GABA, appeared the most likely interfering compound because of the presence of a free primary amine
and a carboxylic acid within its chemical structure that ninhydrin might label analogously to amino acids.
General procedure: A mixture of primary amine
(1 mmol) and formaldehyde (2 mmol, 40% aqueous solution) in 1 mL of methanol was stirred for 5 minutes and to this was added a solution of enaminone 2 (1 mmol) in 4 mL methanol in one portion.
6 times faster with phenyl glycidyl ether (PGE) than the primary amine
Angus Chemical Company, a wholly owned subsidiary of the Dow Chemical Company, introduced an enhanced primary amine
, the AEPD VOX 1000 Multifunctional, for interior water-based paints to the Asia Pacific paint and coatings market during the Asia Pacific Coatings Show in late June.
The N-(N-BOC-aminopropyl) methacrylamide monomer is a solvent-soluble blocked primary amine
monomer that makes accessing amine polymers, especially those containing primary amine
groups, easier for scientists.
AEEA contains a primary amine
and hydroxyl groups on the end of the molecule, with a secondary amine in the center of the ligand.
Reductive amination of B with primary amine
, under a variety of conditions, is currently being explored.
Any primary amine
is a candidate for analysis with this technique," Jacob observes.
