Kiʻekiʻe Kiʻekiʻe Amino Acid Powder L-leucine
Hōʻike huahana
Leucinehe ʻakika amino pono i hoʻohana ʻia i ka biosynthesis o nā protein. ʻO ka leucine he α-amino acid, ʻo ia hoʻi he pūʻulu α-amino (aia i loko o ka protonated −NH.3+ma lalo o nā kūlana olaola), he hui α-carboxylic acid (aia i loko o ka deprotonated −COO−hana ʻia ma lalo o nā kūlana olaola), a me kahi hui isobutyl kaulahao ʻaoʻao, e hoʻolilo iā ia i mea non-polar aliphatic amino acid. He mea nui ia i ke kanaka, ʻo ia hoʻi, ʻaʻole hiki i ke kino ke synthesize ia: pono e loaʻa mai ka meaʻai. ʻO nā kumu meaʻai kanaka he mau meaʻai i loaʻa i ka protein, e like me ka ʻiʻo, nā huahana waiu, nā huahana soy, a me nā pī a me nā legumes ʻē aʻe. Hoʻopili ʻia ia e nā codons UUA, UUG, CUU, CUC, CUA, a me CUG.

Hana
ʻO ka Leucine kahi waikawa amino pono no ka synthesis protein. Eia hou, e like me nā waikawa amino ʻē aʻe, hiki ke hoʻohana ʻia ka iwi kalapona o ka leucine e hana i ka ATP. Eia nō naʻe, hiki i ka leucine ke hoʻoponopono i nā kaʻina cellular e like me ka synthesis protein, ka hoʻoulu hou ʻana o ka ʻiʻo, a me ka metabolism.
