Hana a me ka hoʻohana ʻana o D-Alanine (HD-Ala-OH; D-Ala) (CAS: 338-69-2)
1, ʻO D-Alanine kahi kumu kumu chiral koʻikoʻi, hoʻohana ʻia i ka lāʻau lapaʻau chiral, chiral additives, a ʻo ia ke kumu chiral o chiral synthesis i ka lāʻau lapaʻau a me ka ʻoihana meaʻai.Ma ke ʻano he ʻakika organik me ka hana optical, loaʻa i ka D-Alanine kahi hana hiki ʻole ke hoʻololi ʻia i kekahi mau pūhui kemika chiral asymmetrical hui pū ʻia.A i kēia manawa, hoʻohana ʻia ʻo D-Alanine e hana i ke ʻano hou o ka laulā ākea, D-Alaninol a me ka hoʻohui ʻana i ka ʻono-Alitame hou.
2, He mea nui ka D-Alanine no ka metabolism cell a me ka lawe ʻana i nā meaʻai i loko o ke kino.
3, pili ʻo D-Alanine i ka pōʻai glucose-alanine ma waena o nā kiko a me ke ake.
4, Hoʻohana ʻia ʻo D-Alanine ma ke ʻano he mea maka no ka synthesis o nā mea ʻono hou a me kekahi mau intermediates lāʻau chiral.
5, Hoʻohana nui ʻia ʻo D-Alanine e synthesize pantothenic acid a me ka calcium pantothenate, carnosine, pamidronate, balsalazide, etc., a hoʻohana nui ʻia i ka lāʻau lapaʻau, hānai, meaʻai a me nā māla ʻē aʻe.Hoʻohana ʻia ia i ka electroplating corrosion inhibitors a me nā reagents biochemical.
6, Hoʻohana nui ʻia ʻo D-Alanine ma ke ʻano he meaʻai meaʻai a me ka mea ʻono i ka ʻoihana hana meaʻai.Hiki ke hoʻohana ʻia i ka ʻoihana lapaʻau.
7. He mea hou maikaʻi ko D-Alanine a hiki ke hoʻoikaika i nā hopena o nā mea ʻala kemika;He ʻono ʻokoʻa kona a hiki ke hoʻomaikaʻi i ka ʻono o nā mea ʻono hana, hoʻomaikaʻi i ka ʻawaʻawa o nā waikawa organik a me ka ʻono o ka vīnega;Hiki i kona ʻawaʻawa ke kōkua i ka paʻakai e komo i nā mea kanu, e hoʻomaikaʻi i ka maikaʻi o nā mea kanu paʻakai a i ʻole nā huaʻai ʻai, ʻoki i ka lōʻihi o ka pickling a hoʻomaikaʻi i ka ʻono;
8. Hiki ke hoʻohana ʻia ʻo D-Alanine ma ke ʻano he mea hoʻoponopono a hoʻopaʻa paha i ka haku ʻana i ka waina a i ʻole ka mea inu ʻoluʻolu, hiki ke pale i ka hua waina mai ka wā kahiko a hiki ke hoʻemi i ka ʻala o ka hū;
9. Hiki ke hoʻohana ʻia kāna hana o ka antioxidation i ka hana ʻai.No ka laʻana, hiki ke hoʻohana ʻia i loko o nā aila, yolk jam, nā meaʻai i hoʻomaʻemaʻe ʻia, nā meaʻai i hoʻomoʻi ʻia, a me nā meaʻai i hoʻopaʻa ʻia i ka bra.Hiki iā ia ke pale iā lākou mai ka oxidation a hoʻomaikaʻi i ko lākou ʻono;
10. Hiki ke hoʻohana ʻia ka D-Alanine ma ke ʻano he mea maka no ka synthesis Vitamin B6 a me nā mea no ka noiʻi ʻana i ka metabolism o nā waikawa amino e nā mea ola kino a i ʻole ma ke kumu biochemical.
