Asparagine (symbol Asn or N [2]) is an α-amino acid that is used in the biosynthesis of proteins.It contains an α-amino group (which is in the protonated −NH + 3 form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO − form under biological conditions), and a side chain carboxamide, classifying it as a polar (at physiological pH), aliphatic ...
Potassium asparaginate is a potassium salt of L-asparagine amino acid. [2] [3] [4] [5]Potassium asparaginate can be considered both a salt and a coordination complex. [6] [3] As a salt, potassium asparaginate is formed when the potassium ion (K +) replaces the hydrogen ion (H +) in the carboxyl group of L-asparagine, an amino acid; in this process, the carboxyl group (–COOH) in L-asparagine ...

Deamidation is a chemical reaction in which an amide functional group in the side chain of the amino acids asparagine or glutamine is removed or converted to another functional group. Typically, asparagine is converted to aspartic acid or isoaspartic acid. Glutamine is converted to glutamic acid or pyroglutamic acid (5-oxoproline).
While the conjugate acid of an amine has a pK a of about 9.5, the conjugate acid of an amide has a pK a around −0.5. Therefore, compared to amines, amides do not have acid–base properties that are as noticeable in water. This relative lack of basicity is explained by the withdrawing of electrons from the amine by the carbonyl.
The holidays are a festive time of year. Homes are decorated for the season — Christmas trees, ornaments, poinsettias, and the like. And there are also plenty of holiday treats that are ...
In even slightly acidic conditions, protonation of the nitrogen occurs, changing the properties of histidine and the polypeptide as a whole. It is used by many proteins as a regulatory mechanism, changing the conformation and behavior of the polypeptide in acidic regions such as the late endosome or lysosome , enforcing conformation change in ...
A North Carolina father was arrested Monday after allegedly storming into a high school and choking a teenage student in a caught-on-video attack. Quinton Lofton, 43, was charged with felony ...
