L-Valine
Hoʻolauna
He waikawa amino kaulahao lālā ʻo L-valine, ʻaʻole hiki ke hana ʻia e ke kino holoholona ponoʻī. Pono e ʻai ʻia mai ka ʻai o kēlā me kēia lā e hoʻokō ai i kāna mau pono meaʻai, no laila he waikawa amino koʻikoʻi ia. ʻO nā waikawa amino nā ʻāpana kūkulu kumu o ka hana ʻana o ka protein, nā mea mua o nā amine ʻē aʻe e pono ai no ka metabolism, a he mau mea pono ʻole no ke ola. I kēia manawa, aia he 20 a 30 mau waikawa amino i ʻike ʻia, hiki ke hana ʻia kekahi o ia mau mea i loko o ke kino kanaka a ua kapa ʻia he mau waikawa amino pono ʻole, a ʻaʻole hiki ke hana ʻia kekahi i loko o ke kino kanaka a pono e hoʻohui ʻia mai waho, i kapa ʻia he mau waikawa amino koʻikoʻi.
Nā waiwai kemika
Ua ʻike ʻia ʻo L-valine ʻo 2-amino-3-methylbutyric acid, me ke ʻano kemika C5H11NO2. ʻO kahi kristal monoclinic keʻokeʻo a i ʻole ka pauka crystalline, kahi i hoʻomaʻemaʻe hou ʻia me kahi hopena wai o ka ethanol, he kristal ʻano pā a i ʻole scaly. ʻAʻohe ʻala a he ʻono ʻawaʻawa kūikawā. ʻO ke kiko heheʻe ma kahi o 315 ℃. He maʻalahi ia e hoʻoheheʻe ʻia i ka wai, he waikawa ka hopena wai, a ʻo ka waiwai PH o 5% ka hopena wai he 5.5 ~ 7.0. Aneane hiki ʻole ke hoʻoheheʻe ʻia i ka ethanol a me ka ether. He paʻa ia i ka wela, ka mālamalama a me ka ea. He paʻakikī ke hoʻokaʻawale mai ka leucine.
E HOʻOHANA
He waikawa amino koʻikoʻi ka L-Valine no ke kino o ke kanaka, i hoʻohana ʻia i ka noiʻi biochemical, ka hoʻomākaukau ʻana i ka medium culture tissue, a me nā lāʻau amino acid. Hiki ke hoʻohana ʻia ka tonic meaʻai ma ke ʻano he ʻāpana nui o ka hoʻokomo ʻana o ka waikawa amino a me ka hoʻomākaukau ʻana i ka waikawa ammonia piha. ʻO L-valine kekahi o nā waikawa amino kaulahao ʻekolu. He waikawa amino koʻikoʻi ia, hiki ke mālama i ka hāʻule ʻana o ke akepaʻa a me ka hana ʻole o ka ʻōnaehana nerve waena.
