L-Valine
Chiyambi
L-valine ndi amino acid yopangidwa ndi nthambi, yomwe thupi la nyama silingathe kuipanga. Iyenera kudyedwa kuchokera ku chakudya cha tsiku ndi tsiku kuti ikwaniritse zosowa zake za zakudya, kotero ndi amino acid yofunika kwambiri. Amino acid ndi mayunitsi oyambira a kapangidwe ka mapuloteni, omwe ndi omwe amatsogolera ma amine ena ofunikira kuti kagayidwe kachakudya kagayidwe kachakudya kagayidwe kachakudya kagayidwe kachakudya kagayidwe kachakudya, ndipo ndi zinthu zofunika kwambiri pa moyo. Pakadali pano, pali ma amino acid odziwika 20 mpaka 30, ena mwa iwo amatha kupangidwa m'thupi la munthu ndipo amatchedwa ma amino acid osafunikira, ndipo ena sangapangidwe m'thupi la munthu ndipo ayenera kuwonjezeredwa kuchokera kunja, otchedwa ma amino acid ofunikira.
Kapangidwe ka mankhwala
L-valine imadziwikanso kuti 2-amino-3-methylbutyric acid, yokhala ndi formula ya mankhwala C5H11NO2. Krustalo woyera wa monoclinic kapena ufa wa crystalline, womwe umatsukidwanso ndi yankho lamadzi la ethanol, ndi kristalo wopanda mtundu kapena wooneka ngati mbale. Wopanda fungo ndipo ali ndi kukoma kwapadera kowawa. Malo osungunuka ndi pafupifupi 315℃ Chemicalbook. Amasungunuka mosavuta m'madzi, yankho lamadzi ndi acidic, ndipo PH ya yankho lamadzi la 5% ndi 5.5~7.0. Sasungunuka kwambiri mu ethanol ndi ether. Ndi yokhazikika kutentha, kuwala ndi mpweya. N'zovuta kulekanitsa ndi leucine.
GWIRITSANI NTCHITO
L-Valine ndi amino acid yofunika kwambiri m'thupi la munthu, yomwe imagwiritsidwa ntchito pofufuza za biochemical, kukonza njira yopangira minofu, ndi mankhwala a amino acid. Tonic yopatsa thanzi ingagwiritsidwe ntchito ngati gawo lalikulu la kulowetsedwa kwa amino acid ndi kukonzekera kwathunthu kwa ammonia chemical book-based acid. L-valine ndi imodzi mwa ma amino acid atatu okhala ndi nthambi. Ndi amino acid yofunika kwambiri, yomwe imatha kuchiza kulephera kwa chiwindi ndi kusokonekera kwa dongosolo la mitsempha.
