Application
1. YeKudyisa Giredhi Valine:
L-Valine yakakosha uye yakakosha kudya kwenguruve nehuku se lysine, theonine, methionine uye tryptophan.Mune maitiro eEuropean formula, L-Valine inowanzoonekwa seyechishanu inodzikamisa amino acid.Sezvo isingakwanise kuumbwa mumuviri, inoda kuwedzerwa kubva mukudya.Valine iketani ine matavi amino acid pamwe chete neleucine uye isoleucine, inobatanidzwa mumabasa mazhinji akakosha ebhayoloji.Inogona kubatsira kuvandudza goho remukaka wenguruve inoyamwisa uye kuwedzera immune yemhuka. Kunze kwezvo, Valine inogona kuvandudza kutaurirana kwekudya uye kushanda kweamino acid.
2. Zvekudya Giredhi Valine:
L-Valine iketani ine matavi amino acid, pamwe chete neleucine uye isoleucine, iyo yakakosha kugadzirisa matishu, yenguva dzose glucose yeropa uye inopa simba kumuviri wemunhu, kunyanya kune yakasimba kurovedza muviri.Nokudaro, inogona kushandiswa kunwa kwemitambo.Kunze kwezvo, Valine inogona zvakare kushandiswa sekuwedzera kwechikafu mubheki kuvandudza kunaka kwechikafu.Yakashandawo sezvekudya kunovaka muviri mumaindasitiri ezvekudya nezvinwiwa.Kupfuurirazve, inoita basa rakakosha mukuchengetedza simba repfungwa, kurongeka kwemhasuru uye kugadzikana mupfungwa.L-Valine inokosha amino asidhi inowanikwa mapuroteni;zvakakosha pakukura kwakakwana kwevacheche uye nekukura kwevana uye nitrogen balance muvakuru.
3. Yemushonga Giredhi Valine:
Seimwe yeamino acid infusions, L-Valine inogona kushandiswa kurapa chimwe chirwere chechiropa.Kunze kwezvo, valine ndechimwe chezvinhu zvekutanga zvekugadzira mishonga mitsva.
L-Valine inogona kushandiswa pakutsvagisa biochemical, gadziriro yetishu tsika midhiya.L-Valine inoshandiswawo seamino acids mishonga inovaka muviri mukurapa.
L-Valine yakanakirawo kugadzirisa mhando yeamino acid kushomeka kunogona kukonzerwa nekupindwa muropa nezvinodhaka.
