Hoʻohana
Hoʻohana ʻia ma ke ʻano he substrate no nā transaminase a me nā dehydrogenase assays, ke kākoʻo ʻana i ka reagent no nā hoʻokolohua hana ate, a me ka waena i ka synthesis organik.
Hoʻohana ʻia ma ke ʻano he reagent analytical no ka tryptophan; substrate no ka hoʻoholo ʻana o ka transaminase a me ka dehydrogenase; reagent kōkua no nā hoʻokolohua hana ate.
He mea i hana ʻia mai ka waikawa valeric, he mea waena ia i loko o ke kaʻina hana Krebs i hoʻoulu ʻia e ka glutamate dehydrogenase.
Hiki ke hoʻohana ʻia ka waikawa α-Ketoglutaric ma ke ʻano he mea maka no nā lāʻau lapaʻau, nā huahana mālama ola kino a me nā mea hoʻohui meaʻai.
ʻŌpala a me ka Hoʻouna ʻana
25KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
