Hoʻolauna

ʻO ka L-leucine kahi amino acid kekahi o nā poloka kūkulu o nā protein. He paʻa kala kala ʻole ia i hiki ke hoʻoheheʻe ʻia i ka wai.

 

ʻElua mau ala nui no ka hoʻomākaukau ʻana i ka L-leucine: ke ʻano kūlohelohe a me ke ʻano synthesis kemika. Hoʻohui pinepine ʻia nā ʻano kūlohelohe e ke kaʻina fermentation o nā microorganisms, e like me ka bacteria. Hoʻomākaukau ʻia ke ʻano hana synthesis kemika ma o ke ʻano o nā hopena synthesis organik.

 

ʻIke palekana o L-Leucine: L-Leucine he palekana ma ka laulā. Hiki i ka ʻai nui ʻana ke hōʻeha i ka ʻōpū o ka ʻōpū, ka diarrhea, a me nā hōʻailona ʻē aʻe. No ka poʻe me ka lawa ʻole o ka renal a i ʻole ka metabolic abnormalities, pono e mālama ʻia e pale i ka lawe nui ʻana.
