I-L-Valine
Intshayelelo
I-L-valine yi-amino acid ene-branched-chain, engenakwenziwa ngumzimba wesilwanyana ngokwawo. Kufuneka ityiwe kwisondlo semihla ngemihla ukuze ihlangabezane neemfuno zayo zesondlo, ngoko ke yi-amino acid ebalulekileyo. Ii-amino acids ziiyunithi ezisisiseko zokwenziwa kweproteni, ezandulela ezinye ii-amines ezifunekayo kwi-metabolism, kwaye zizinto eziyimfuneko ebomini. Okwangoku, kukho ii-amino acid ezingama-20 ukuya kuma-30 ezaziwayo, ezinye zazo ezinokwenziwa emzimbeni womntu kwaye zibizwa ngokuba zii-amino acids ezingezizo ezibalulekileyo, kwaye ezinye azinakwenziwa emzimbeni womntu kwaye kufuneka zongezwe ngaphandle, ezibizwa ngokuba zii-amino acids ezibalulekileyo.
Iimpawu zekhemikhali
I-L-valine ikwaziwa ngokuba yi-2-amino-3-methylbutyric acid, enefomyula yekhemikhali i-C5H11NO2. Ikristale emhlophe ye-monoclinic okanye i-crystalline powder, ecocwa kwakhona ngesisombululo samanzi se-ethanol, yikristale engenambala okanye enamaxolo. Ayinavumba kwaye inencasa ekhethekileyo ekrakra. Indawo yokunyibilika imalunga ne-315℃ Chemicalbook. Inyibilika lula emanzini, isisombululo samanzi sine-asidi, kwaye ixabiso le-PH lesisombululo samanzi se-5% yi-5.5~7.0. Phantse ayinyibiliki kwi-ethanol nakwi-ether. Izinzile kubushushu, ekukhanyeni nasemoyeni. Kunzima ukwahlula kwi-leucine.
SEBENZISA
I-L-Valine yi-amino acid ebalulekileyo emzimbeni womntu, esetyenziswa kuphando lwe-biochemical, ukulungiswa kwe-tissue culture medium, kunye namayeza e-amino acid. I-tonic yesondlo ingasetyenziswa njengeyona nto iphambili ekufakweni kwe-amino acid kunye nokulungiswa kwe-asidi esekwe kwi-ammonia chemical book-based. I-L-valine yenye yee-amino acid ezintathu ezine-branched-chain. Yi-amino acid ebalulekileyo, enokunyanga ukungasebenzi kakuhle kwesibindi kunye nokungasebenzi kakuhle kwenkqubo ye-nervous system.
