L-Asparagine | 5794-13-8
Hōʻike huahana:
ʻO ka L-Asparagine kahi mea kemika me ka helu CSA o 70-47-3 a me ke kumu hoʻohālikelike o C4H8N2O3. ʻO ia kekahi o nā waikawa amino 20 i loaʻa mau i nā mea ola.
Hoʻokaʻawale ʻia ia mai nā ʻāpana wai o ka lupine a me ka soybean sprouts me ka L-asparagine kiʻekiʻe. Loaʻa ia ma ka amidation o L-aspartic acid a me ammonium hydroxide.
ʻO ka maikaʻi o L-Asparagine:
Hiki i ka Asparagine ke hoʻonui i ka bronchi, hoʻohaʻahaʻa i ke koko, hoʻomāhuahua i nā kīʻaha koko, hoʻonui i ka helu systolic cardiac, hoʻemi i ka puʻuwai puʻuwai, hoʻonui i ka mimi, hoʻonohonoho i ka pōʻino mucosal ʻōpū, loaʻa kekahi mau hopena antitussive a asthmatic, anti-fatigue, a hoʻonui i ka pale.
Hoʻoulu i nā microorganism.
Hoʻomaʻemaʻe wai.
