Asparagine [chizindikiro cha Asn kapena N] ndi kiyi α-amino acid yomwe imagwiritsidwa ntchito mu biosynthesis ya mapuloteni.Lili ndi gulu la α-amino ndi gulu la α-carboxylic acid komanso mbali ya carboxamide.Imagawidwa ngati polar [pa physiological pH], aliphatic amino acid.Ndizosafunikira mwa anthu, ndipo zimatha kupangidwa ndi de novo synthesis mkati mwa thupi la munthu.Kuchokera pamtundu wa ma genetic code panthawi ya protein synthesis, imasungidwa ndi ma codon AAU ndi AAC.L-Asparagine ndi chochokera ku aspartate chosatulutsidwa.
Kugwiritsa ntchito L-Asparagine Anhydrous (Asn Anhydrous) (CAS: 70-47-3)
1. Mu mankhwala, L-Asparagine angagwiritsidwe ntchito pofuna kuchiza matenda a mtima, matenda a chiwindi, matenda oopsa, ndi zotsatira za kupewa ndi kubwezeretsa kutopa.Pamodzi ndi mitundu yosiyanasiyana ya amino acid, imatha kupangidwa kukhala kulowetsedwa kwa amino acid, komwe kumagwiritsidwa ntchito ngati ammonia antidote, wolimbikitsa ntchito ya chiwindi, wobwezeretsa kutopa.
L-Asparagine ndi mankhwala omwe amagwiritsidwa ntchito pochepetsa kuthamanga kwa magazi, kukulitsa bronchus (asthma), anti-peptic ulcer ndi kusagwira bwino ntchito kwa m'mimba.Kuchepetsa kuthamanga kwa magazi, kufutukuka kwa bronchus (asthma), anti-peptic ulcer ndi kusagwira ntchito bwino kwa m'mimba.Ntchito tizilombo chikhalidwe, zimbudzi mankhwala acrylonitrile, etc.
2. M'makampani a zakudya, L-Asparagine ndi chakudya chabwino chopatsa thanzi, chowonjezeredwa ku zakumwa zoziziritsa kukhosi zosiyanasiyana;Ndiwonso zopangira zazikulu za sweet monosodium glutamate (aspartame) -aspartate phenylalanine methyl ester.
Asparagine ali ndi ntchito yabwino yowulula mwatsopano komanso kusunga.L-Asparagine imagwiritsidwa ntchito kwambiri ngati mankhwala opangira mankhwala kapena kuwulula zatsopano komanso zophatikizika pantchito yazakudya, ndipo zimatha kulowa m'malo mwa monosodium glutamate.
3. Mumakampani opanga mankhwala, L-Asparagine angagwiritsidwe ntchito ngati zopangira za utomoni wopangira komanso ngati chowonjezera chopatsa thanzi cha zodzoladzola.
