Ntchito Ndi Kugwiritsa Ntchito D-Alanine (HD-Ala-OH; D-Ala) (CAS: 338-69-2)
1, D-Alanine ndi gwero limodzi lofunikira la chiral, limagwiritsidwa ntchito ngati mankhwala a chiral, zowonjezera za chiral, ndipo ndi chiral gwero la chiral synthesis m'makampani opanga mankhwala ndi zakudya.Monga organic acid imodzi yokhala ndi kuwala, D-Alanine imakhala ndi ntchito yosasinthika mumitundu ina yamankhwala asymmetrical kuphatikiza motsatizana.Ndipo tsopano, D-Alanine amagwiritsidwa ntchito kupanga mtundu watsopano wa sipekitiramu yotakata, D-Alaninol ndi kutsekemera kwatsopano-Alitame.
2, D-Alanine ndiyofunikira kuti kagayidwe ka cell ndi kayendedwe ka michere m'thupi.
3, D-Alanine imagwira nawo gawo la glucose-alanine pakati pa minofu ndi chiwindi.
4, D-Alanine imagwiritsidwa ntchito ngati zopangira popanga zotsekemera zaposachedwa komanso zapakati pamankhwala a chiral.
5, D-Alanine zimagwiritsa ntchito pantothenic asidi ndi kashiamu pantothenate, carnosine, pamidronate, balsalazide, etc., ndipo chimagwiritsidwa ntchito mankhwala, chakudya, chakudya ndi zina.Amagwiritsidwanso ntchito mu electroplating corrosion inhibitors ndi biochemical reagents.
6, D-Alanine imagwiritsidwa ntchito makamaka ngati zakudya zowonjezera komanso zokometsera m'makampani opanga zakudya.Itha kugwiritsidwanso ntchito m'makampani azachipatala.
7. D-Alanine ali ndi kutsitsimuka bwino ndipo akhoza kulimbikitsa zotsatira za flavorings mankhwala;Ili ndi kutsekemera kwapadera ndipo imatha kusintha kukoma kwa zotsekemera zopangira, kumapangitsanso kutsekemera kwa ma organic acid ndi kukoma kwa vinyo wosasa;Kuwawa kwake kungathandize mchere kulowa masamba, kusintha khalidwe la mchere kapena msuzi-kuzifutsa masamba, kuchepetsa nthawi pickling ndi kusintha kukoma;
8. D-Alanine angagwiritsidwe ntchito monga corrector kapena nkhokwe mu zikuchokera vinyo kapena zofewa chakumwa, angalepheretse kuwira vinyo ku ukalamba ndipo akhoza kuchepetsa fungo la yisiti;
9. Ntchito yake ya antioxidation ingagwiritsidwe ntchito pokonza chakudya.Mwachitsanzo, itha kugwiritsidwa ntchito mumafuta, jamu la yolk, zakudya zoyeretsedwa, zakudya zokazinga msuzi, ndi zakudya zokazinga.Zitha kuwateteza ku okosijeni ndikuwongolera kukoma kwawo;
10. D-Alanine angagwiritsidwe ntchito ngati zopangira kwa Vitamini B6 kaphatikizidwe ndi zakuthupi kafukufuku kagayidwe wa amino zidulo ndi zamoyo zachipatala kapena zamoyo maziko.
