Taupānga

L-Valine taapiri kai. Ko te whaowhia waikawa amino me nga whakaritenga waikawa amino matawhānui ka taea te whakarite tahi me etahi atu waikawa amino tino nui. Tāpirihia te valine (1g,/kg) ki ngā keke raihi, ā, he kakara hāmana te hua. Ka taea hoki te whakapai ake i te reka o te taro ina whakamahia. Ko L-Valine tetahi o nga waikawa amino mekameka e toru, he waikawa amino tino nui hei rongoa i te ngoikoretanga o te ate me te ngoikoretanga o te punaha io.
