Daim Ntawv Thov

L-Valine cov khoom noj khoom haus ntxiv. Kev sib xyaw ua ke ntawm cov amino acid thiab cov amino acid npaj txhij tuaj yeem npaj ua ke nrog lwm cov amino acids tseem ceeb. Ntxiv valine (1g,/kg) rau hauv cov ncuav mog qab zib, thiab cov khoom muaj ntxhiab tsw qab ntawm cov noob hnav. Nws kuj tseem tuaj yeem txhim kho qhov saj ntawm cov mov ci thaum siv. L-Valine yog ib qho ntawm peb cov amino acids branched chain thiab yog cov amino acid tseem ceeb uas tuaj yeem kho qhov ua tsis tau zoo ntawm daim siab thiab kev ua haujlwm tsis zoo ntawm lub paj hlwb.
