Kushandisa Zvigadzirwa
L-valine ndiyo makristasi machena kana crystalline poda, chibhakera chinotapira chinotapira uye chinovava zvishoma. Yakasununguka kunyungudika muformic acid, inonyungudika mumvura, isinganyungudika mu ethanol uye ether. Uye iyo yakakosha amino acid inodiwa kune yakatsetseka tsinga sysytem uye cognitive basa. Icho chimwe chevatatu Mapazi China Amino Acids (BCAAs). L-Valine haigoni kubudiswa nemuviri uye inofanira kuiswa kuburikidza nezvokudya kana kuwedzera. nhengo dzose dzomuviri dzinoda. Valine inogona kushandiswa sekuwedzera kwekudya, inogona kuve yakabatanidzwa pamwe nemamwe amino acid infusion, yakazara amino acid kugadzirira.
L-Valine inoshandiswa semishonga mbishi zvinhu kana yekuwedzera chikafu.
