ʻO Asparagine [hōʻailona Asn a i ʻole N] he kī nui α-amino acid i hoʻohana ʻia i ka biosynthesis o nā protein.Loaʻa iā ia kahi hui α-amino a me kahi hui α-carboxylic acid a me kahi carboxamide kaulahao ʻaoʻao.Hoʻokaʻawale ʻia ʻo ia ma ke ʻano he polar [ma ka pH physiological], aliphatic amino acid.ʻAʻole pono ia i ke kanaka, a hiki ke hana i ka de novo synthesis i loko o ke kino kanaka.Mai ke ʻano o ka genetic code i ka wā o ka synthesis protein, ua hoʻopili ʻia e nā codons AAU a me AAC.ʻO L-Asparagine kahi mea i hoʻoili ʻole ʻia o ka aspartate.
Hoʻohana i ka L-Asparagine Anhydrous (Asn Anhydrous) (CAS: 70-47-3)
1. I ka lāʻau lapaʻau, hiki ke hoʻohana ʻia ʻo L-Asparagine e mālama i ka maʻi maʻi puʻuwai, ka maʻi ate, ka hypertension, me ka hopena o ka pale a hoʻihoʻi i ka luhi.Me nā ʻano waikawa amino like ʻole, hiki ke hana ʻia i loko o ka infusion amino acid, hoʻohana ʻia e like me ka ammonia antidote, ka mea hoʻoulu hana ate, ka mea hoʻōla luhi.
ʻO ka L-Asparagine kahi lāʻau lapaʻau i hoʻohana ʻia no ka hoʻohaʻahaʻa ʻana i ke koko, ka hoʻonui ʻana i ka bronchus (asthma), anti-peptic ulcer a me ka maʻi ʻōpū.ʻO ka hoʻohaʻahaʻa ʻana i ke koko, ka hoʻomāhuahua ʻana o ka bronchus (asthma), anti-peptic ulcer a me ka hana ʻole o ka ʻōpū.Hoʻohana ʻia no ka moʻomeheu microbial, ka mālama ʻana i ka wai o ka acrylonitrile, etc.
2. I loko o ka ʻoihana meaʻai, L-Asparagine kahi meaʻai meaʻai maikaʻi, hoʻohui ʻia i nā ʻano mea inu ʻoluʻolu;ʻO ia hoʻi ke kumu nui o ka monosodium glutamate (aspartame)-aspartate phenylalanine methyl ester.
He hana maikaʻi ʻo Asparagine e hōʻike i ka mea hou a me ka mālama ʻana.Hoʻohana nui ʻia ʻo L-Asparagine ma ke ʻano he lāʻau lapaʻau a i ʻole e hōʻike ana i ka mea hou a me ka antiseptic i ka ʻoihana meaʻai, a hiki ke hoʻololi i ka monosodium glutamate.
3. Ma ka ʻoihana kemika, hiki ke hoʻohana ʻia ʻo L-Asparagine e like me ka mea maka o ka resin synthetic a me ka mea hoʻohui meaʻai o nā mea hoʻonaninani.
