Muaj peb txoj hauv kev sib txuas cov amino acids, leucine, isoleucine, thiab valine. Peb cov branched-chain amino acids tseem ua ib feem peb ntawm cuajcov amino acids tseem ceebuas yuav tsum tau noj hauv peb cov zaub mov noj lossis los ntawm cov tshuaj ntxiv.
Muaj ntau qhov kev txaus siab tsim nyob ib puag ncig cov saw hlau amino acids tom qab kev tshawb fawb ntxov pom tias peb cov amino acids no muaj peev xwm tshwj xeeb los txhawb cov leeg nqaij cov protein sib txuas, cov txheej txheem xav tau rau kev loj hlob thiab kho cov leeg. Leucine tshwj xeeb, yog tus ua ntej ncaj qha rau cov leeg nqaij ua kom muaj protein ntau (xav txog nws li ntawm qhov hloov pauv) thiab tswj hwm tus lej ntawm anabolic teeb liab qhia txoj hauv kev uas koom nrog cov protein synthesis.
Nws yog ib qho tseem ceeb kom nco ntsoov, txawm li cas los xij, qhov tseem ceeb ntawm kev tshawb fawb qhia pom qhov sib txuas zoo ntawm branched-chain amino acid kom tau txais thiab cov leeg nqaij protein synthesis tau ua hauv cov nas (txwv tsis pub siv rau tib neeg cov protein synthesis cov lus teb), thiab txawm hais tias cov leeg nqaij protein synthesis tuaj yeem nce nrawm heev tom qab noj cov nas, cov txiaj ntsig yog qhov luv.
