He aha e nā'ūhū

I kekahi mea ola meaola - ia mea he hemolele'ōnaehana, ma i na minuke loaʻa nō kekahi Nine Inch reactions. hiki ole mau keʻano o ka hanaʻana hana me ke komo 'ana o nā'ūhū. No laila, i ka mea a mau nā'ūhū? He aha kā lākou kūlana ma ke ola o ka meaola? He aha mau mea? He aha ka keʻano papa hana o ko lākou mau waiwai? Aia ma lalo nā pane i kēia mau nīnau a pau.

He aha e nā'ūhū?

Nā'ūhū, paha, e like me ka mea i kapaʻia, nā'ūhū i kumuʻiʻo eiiieaenu. He biologically hana waiwai, a hana like catalysts o Nine Inch reactions. I mea, i ke kūlana o nā'ūhū mea paakiki e overestimate, no ka mea, me ia hiki ole ke hana i kekahi kaʻina hana i loko o ka halepaahao ola a me ka meaola a pau.

Ka manawa "'ūhū" Ua manaoia ma ka 17th kenekulia i kaulana chemist Helmont. A eia nae i ike na haumana nui o ka manawa e ai ua hōʻuluʻulu manaʻo i loko o ke alo o gastric wai, a me ka pia ma ka tuha, mai hemo mai ia i na mea o nā mahi kō,ʻaʻohe kekahi i ike i ka mea i kauoha ae la ia e like keʻano o ka hanaʻana. Akā, i loko o ke kakahiaka nui 19th kenekulia, Kirchhoff mua hōʻike 'ia ma salivary nā'ūhū - amylase. A mau makahiki ma hopeʻo ia i ho'ākāka 'ia ma gastric pepsin. Mai laila, ka 'epekema o ka enzymology hoomaka ae la i ka' Imi hoʻomōhala.

He aha e nā'ūhū? Ka waiwai a meʻano papa hana o ka hoʻokō '

No ka hoʻomaka ka mea, o kona waiwai 'ana i kumumanaʻo mea a pau nā'ūhū i nā polokina kekahi i loko o ke gula palapala a kumuʻiʻo eiiieaena. I ka lā, i ka ho oholo'aminoʻakika kaʻina o ka hapanui o na nā'ūhū o ke kanaka kino.

I ka papa kuhikuhiE waiwai o nā'ūhū - he kiʻekiʻe specificity. Kēlā me kēia'ūhū e catalyze hoʻokahi wale nō 'ano o ka naoh. No ka laʻana, proteolytic nā'ūhū hiki wale hoopili linkages ma waena o'aminoʻakika residues o ke kumuʻiʻo lātoma. I kekahi manawa, hoʻokahi kūpapakū (mea waiū'ūhū) ke loli mau structurally like nā'ūhū.

Naʻe, i ka'ūhū paha e ho'ākāka ole wale i ka naoh, akā, i ka pili ana i ka kūpapakū. Ka loa e like me ka pūʻulu specificity o nā'ūhū. Kēia 'o ia hoʻi i ka kekahi'ūhū hiki ke loli wale i kekahi pūʻulu o substrates i i ka like' ole.

Akā, i kekahi manawa, aia no ua ai-kapaia loa specificity. Kēia 'o ia hoʻi i ka'ūhū ke hoopaa i kaʻeleu paena o hoʻokahi wale nō kūpapakū. O ka papa, ma ke ano o keia specificity mea pohihihi keia. Akā, no ka laʻana, ua hiki ke hoole i ka'ūhū urease, a hiki catalyze wale ka hydrolysis o ka urea.

Ano, ua ike makou i na nā'ūhū. Akā, i kēia mau waiwai hiki e heʻokoʻa. No laila, ka mea i ana hoʻolaha.

Mea Maluna o nā'ūhū

Hoikehonua, 'epekema ike mau tausani oi ma mua o nā'ūhū, akā, i kēia mea,ʻaʻole ka mea kiko'ī helu. No ka pākuʻi pono, ka mea, ua mahele ia i loko o ka papa kuhikuhiE pūʻulu eono, ke kaumaha ma muli o ka catalyzed naoh.

• Oxidoreductases - he pūʻulu o nā'ūhū e komo ai i loko o redox reactions. IeAUPIIe, IAa IO, ka mea hana aku i kekahi nā mea hāʻawi 'ole acceptors o electrons a me hydrogen Ion. Mau nā'ūhū i mea nui, mai ka keʻano o ka hanaʻana i loko o kākou aeea pūnao a me ka mitochondrial ka hanu.
• Transferase - nā'ūhū i ka pae'āina ma ka hoolilo ana i'ātoma pūʻulu mai kekahi kūpapakū i kekahi. Komo i loko o ka palapala pūnao.
• Lyase - na nā'ūhū hiki ke hoopili aku i ka kūpapakū mai'ātoma pūʻulu me ka hydrolytic naoh. Nui, e like me ka hopena o kēia kaʻina hua mai la i ka wai lātoma paha o carbon dioxide.
• Hydrolase - he'ūhū e catalyzes ka hydrolytic cleavage o ka kūpapakū me ka hoʻohana 'ana o ka wai lātoma.
• Isomerase - like me ka inoa paipai, mau nā'ūhū catalyze i ka huli ana o ka mea mai kekahi isomeric palapala i kekahi.
• Ligases - nā'ūhū i catalyze ka kemikala naoh.

I hiki ke ike, nā'ūhū - i kēia mau mea nui loa no ke kino i nā puke, me ka a na keʻano o ka hanaʻana o ke ola i wale hiki ole.
