The nitro group of the compound 3 was then reduced to the amino group
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 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.
Fluctuations of in-coordinate amino group
are fit with absorption bands at 3290.
In DNA's double helix, cytosine always pairs with guanine, but when the amino group
disappears, the damaged remains tend to pair with adenine--which can cause a mutation if the defect persists.
Ninhydrin assay was used to determine the free amino group
concentration of each test sample as per the procedure of Sung et al.
Therefore guanylation of the side-chain amino group
of aza-ornithine, already included into peptide sequence, was used in the first attempt to synthesize the aza-arginine containing peptidomimetics .
GM Global Technology Operations has been granted a patent for a polymer comprised of a reaction product of an epoxy resin; a first crosslinking agent reactive with the epoxy resin and having a first molecular weight; and a second crosslinking agent reactive with the epoxy resin, wherein the second crosslinking agent is an amine having a polyether backbone, at least one amino group
attached to the polyether backbone, and a second molecular weight of at least 2.
It is well known that many amino acids could produce a polypeptide through dehydration-condensation reaction between a primary amino group
of one amino acid and a carboxyl group of another amino acid, and several polypeptides would further form a protein.
MAPRes is an efficient tool which has been utilized to mine significant residues and assCiation patterns for surrounding amino acids of some specific modifications on hydroxyl and amino group
such as phosphorylation and acetylation.
of Connecticut-Storrs) offers a representative overview of the synthesis of amino acids in which the amino group
is not on the carbon immediately adjacent to the carboxyl group--the alpha position--but is attached to another carbon in the chain--somewhere further down the Greek alphabet.
