Peptidase . Peptidase yog tseem hu ua protease lossis proteinase. Lawv raug tsim tawm hauv plab, hnyuv me thiab txiav txiav thiab yog lub luag haujlwm rau kev tshem tawm cov peptide sib txuas ntawm cov amino acids los ntawm cov tshuaj tiv thaiv hydrolysis, raws li qhia hauv daim duab 1. Yog li, lawv muaj lub luag haujlwm hauv kev zom cov protein hauv lub cev.
Dhau li, cov khoom lag luam ntawm peptidase yog dab tsi?
4) Mus rau INTESTINE me me (duodenum ile ileum)
| SUBSTRATE | KHOOM | ENZYME |
|---|---|---|
| Maltose | Ntshav qab zib | Maltase |
| Cov protein | Me polypeptides | Endopeptidase: trypsin |
| Me polypeptides | Amino acids; Dipeptides | Exopeptidase |
| Dipeptides | Cov amino acids | Peptidase |
Ib sab saum toj no, peptidase substrate yog dab tsi? A peptidase tshuaj cleav a txheej ntawm daim ntawv cog lus scissile, thiab txheej cov seem ntawm ob sab ntawm daim ntawv cog lus no hu ua P1 thiab P1 '. Los ntawm kev paub qhov twg hauv cov protein, peptides lossis hluavtaws substrates cleavages tshwm sim, nws muaj peev xwm ua kom pom qhov tshwj xeeb ntawm a peptidase tshuaj.
Hauv kev hwm rau qhov no, peptidase ua haujlwm li cas?
Peptidase, tseem hu ua protease lossis proteolytic yog ib qho enzyme nrog lub luag haujlwm tseem ceeb hauv kev hydrolysis ntawm cov protein . Hydrolysis yog txheej txheem zom cov molecules loj rau hauv qhov me me, hauv qhov no los ntawm cov protein muab peptides thiab txawm tias chav me me hu ua cov amino acids.
Peptidases ua dab tsi rau cov zaub mov hauv txoj hnyuv me?
Txhuam txhuam ntawm hnyuv me yog nruab nrog tsev neeg ntawm peptidases . Lawv ua haujlwm ntxiv rau hydrolysis ntawm lumenal peptides, hloov lawv mus rau cov amino acids dawb thiab ntau heev me me peptides. Cov khoom kawg ntawm kev zom zaub mov, tsim nyob rau saum npoo ntawm enterocyte, yog npaj rau kev nqus.

Dab tsi yog lub npe ntawm cov khoom tsim uas yog qhov tseem ceeb rau kev pib tsim cov ntshav khov?
Thrombocytes (platelets) Megakaryocytes tsim los ntawm hemocytoblasts hauv cov pob txha liab. Thrombocytes dhau los ua nplaum thiab sib sau ua ke los ua cov platelet ntsaws uas kaw qhov tawg thiab kua muag hauv cov hlab ntshav. Lawv kuj pib tsim cov ntshav txhaws
Nyob rau theem dab tsi ntawm kev tsim cov kab mob fungal yog diploid cells tsim?
Hauv lub neej voj voog ntawm kev sib deev kis tus kab mob hu ua fungus, theem haploid hloov nrog qib diploid. The haploid theem xaus nrog nuclear fusion, thiab theem diploid pib nrog kev tsim zygote (diploid cell ua los ntawm fusion ntawm ob haploid cells)
Thaum ib tus tswv ntiav haujlwm tau txais OSHA qhov kev hais tawm Qhov twg lawv yuav tsum tshaj tawm daim ntawv theej ntawm qhov kev hais tawm?
Yuav Tsum Tau Xa Ntawv Thaum koj tau txais OSHA Daim Ntawv Ceeb Toom, koj yuav tsum tshaj tawm nws (lossis daim ntawv theej ntawm nws) ntawm lossis ze qhov chaw uas txhua qhov kev ua txhaum tshwm sim los ua rau cov neeg ua haujlwm paub txog qhov phom sij uas lawv yuav raug nthuav tawm. Tsab ntawv ceeb toom OSHA yuav tsum tau tshaj tawm rau 3 hnub ua haujlwm lossis kom txog thaum qhov kev phom sij raug txo, qhov twg yog qhov ntev dua
Dab tsi yog creatinine thiab nws tsim tawm li cas?
Creatinine yog tsim los ntawm creatine, cov txheej txheem tseem ceeb rau kev tsim hluav taws xob hauv cov leeg. Creatinine tau thauj los ntawm cov hlab ntshav mus rau ob lub raum. Lub raum lim tawm feem ntau ntawm creatinine thiab pov tseg nws hauv cov zis. Txawm hais tias nws yog pov tseg, creatinine ua haujlwm tseem ceeb rau kev kuaj mob
Cov kab mob hauv qhov ncauj dab tsi metabolize sucrose tsim cov nplaum glucans thiab tsim cov quav hniav?
GTF yog qhov tseem ceeb enzyme uas catalyzes sucrose rau nplaum glucans thiab pab txhawb kev tsim cov hniav plaque nyob rau hauv uas lub tsub zuj zuj ntawm metabolic acids uas ua los ntawm cov kab mob colonies ua rau lub zos demineralization ntawm cov enamel nto (Loesche, 1986)
