Such type of covalent chemical bonds are formed when the carboxyl group of one amino acid reacts with the amino group of another.
An amino functional group that is within a pendant group of coupling agents is widely used for GF/nylon composites because the amine end groups of polyamide molecules form a hydrogen bond with the amino group.
Acetyl group of trifluoroacet- ylacetone (FAA) might react with primary amino group to create Schiff base and extended carbon chain with CF3 group could enhance the volatility of the derivative.
Moreover, the amino group on the surface of CNPs can be used for attachment of antibody.
The second additive was NMA, which is a polar substance with a benzene ring and amino group. The fuel blended with NMA had an extremely high research octane number (RON) of 106, which demonstrates the significant octane number improvement effect of this additive.
mainly arginine and lysine) contain an additional amino group, which is protonated at body pH, and their metabolism leads to the production of acid."
It was found that the trifluoroacetic acid is the most suitablej for completely dissolving the two polymers, dissolution was achieved in two stages, the first is by protonation of the amino groups (-NH2) along both polymer chains; second was by ionic interaction between the protonated amino group (-NH 3) and the anionic groups of trifluoroacetic acid (Sangsanoh & Supaphol, 2006).
The internal aldimine Schiff-base linkage between PLP and the amino group of active site Lys residue switches back and forth to the external aldimine Schiff-base linkage between PLP and the substrate amino group in the middle of catalysis.
The solution approach was therefore ruled out in favor of amide bond formation between the Asp side-chain carboxyl of resin-bound 4 and a suitably protected version of PMM with a single free amino group.
The free amino group of DOPE was converted into mercaptobutyrimidyl group using 2-iminothiolane (2-IT or Traut's reagent, SigmaAldrich, Hungary) [29-31].
Taking into account the fact that jatrorrhizine and berberine belong to quaternary protoberberine alkaloid (QPA), we report the design, synthesis, and biological evaluation of a series of novel jatrorrhizine derivatives which have an amino group linked at the 3-position as both AChE and BuChE inhibitors in this paper, hoping that these derivatives could be used as agents for Alzheimer's disease (AD).
The functional group II is a nitrogen-containing group in which both of two hydrogen atoms of a primary amino group are substituted with protective groups.
