Hoʻolauna

 

He ʻano koʻikoʻi ko D-histidine i nā mea ola. He waikawa amino koʻikoʻi ia he mea nui e pono ai no ka ulu a me ka hoʻoponopono ʻana i ka ʻiʻo ʻiʻo. Loaʻa iā D-histidine ka hopena o ka hoʻomaikaʻi ʻana i ka ikaika o ka ʻiʻo a me ka hoʻomanawanui a me ka hoʻoikaika ʻana i ka synthesis protein. Hoʻohana nui ʻia ia i nā mea hoʻohui kino a me nā haʻuki.

 

ʻO ka hoʻomākaukau ʻana o D-histidine ka mea nui ma o ka synthesis kemika a i ʻole biosynthesis. Hoʻohana mau ʻia ke ʻano hana chiral synthesis i ka synthesis kemika, a mālama ʻia nā kūlana hopena a me ke koho catalyst, i hiki i ka huahana synthesis ke loaʻa ka histidine i ka hoʻonohonoho D-stereo. Hoʻohana ʻo Biosynthesis i nā ala metabolic o nā microorganism a i ʻole hū e synthesize D-histidine.

Ma ke ʻano he meaʻai meaʻai, palekana ke ʻano o D-histidine. Inā ʻoi aku ka nui o ka nui i ʻōlelo ʻia a hoʻohana ʻia paha i nā koina kiʻekiʻe no ka manawa lōʻihi, hiki ke hōʻeha i nā hopena ʻaoʻao e like me ka ʻeha o ka ʻōpū, ke poʻo, a me nā hopena maʻi. Eia kekahi, pono e hoʻohana ʻia ka D-histidine me ka akahele i kekahi mau heluna kanaka, e like me nā wahine hāpai a lactating paha, nā mea maʻi me ka lawa ʻole o ka renal, a i ʻole phenylketonuria.
