Methyl D-alaninate hydrochloride is the axiological assemblage of
protein, is one of 21 kinds of amino acerbic agreement of animal
proteins. The amino acerbic agreement of protein molecules are L- amino
acid. Because they are in the aforementioned pH, the answerable
accompaniment of assorted amino acids is different, with altered
isoelectric point ( PI ), which is the assumption of electrophoresis and
chromatography in the break of amino acids. Alanine with alanine and β -
alanine two isomers. Alanine, - amino acid. More than 200 ℃sublimation,
with altered heating ante about in the atomization of amid 264 ~ 296 ℃.
Is a basic of protein. Is the animal physique non capital amino acids
in nutrition. At present, abounding from the beverage and abstraction of
accustomed products. β - alanine or 3 amino acid, achromatic crystals.
Melting point 198 ℃( atomization ), acrid in water, hardly acrid in
ethanol, baffling in ether. For the amalgam of pantothenic acerbic and
electroplating, aswell acclimated in the abstraction of Microbiology and
biochemistry and so on, by the hydrolysis of sericin, gelatin, zein
protein and refined, aswell acclimated actinic amalgam method.
Methyl D-alaninate hydrochloride is acclimated for the amalgam of new
aspartame and some chiral biologic average raw materials. The blockage
of branch stones, abetment in glucose metabolism, helps to abstinent
hypoglycemia, advance the physique energy. Take the artefact of about
80mg, accurately weighed, and anhydrous formic acerbic attenuated in
2ml, arctic acerb acerbic is 30ml, as abeyant titration adjustment (
Appendix VII A ), with perchloric acerbic titration band-aid ( 0.1mol/L )
titration, and will use the bare beginning arrangement results. Each
1ml perchloric acerbic titration band-aid ( 0.1mol/L ) is agnate to
8.909mg C3H7NO2. Calibration: in two potassium formic acerbic and
105℃drying to connected weight criterion phthalate is about 0.16g,
accurately weighed, and anhydrous 20mL acerb acerbic dissolving, abacus
clear violet indicator band-aid 1 drops, the aqueous boring titrated to
blue, and the titration after-effects with bare correction. Each 1mL
perchloric acerbic titration band-aid ( 0.1mol/L ) of phthalic acerbic
potassium hydrogen two is agnate to 20.42mg. According to the dosage of
potassium hydrogen two formic acerbic burning of the band-aid and the
absorption of benzene, account the fluid.
