Qhov sib txawv tseem ceeb ntawm somatostatin thiab somatotropin yog tias somatostatin yog ib qho kev loj hlob hormone-inhibiting hormone uas ua haujlwm raws li somatotropin tso tawm inhibiting yam. Lub caij no, somatotropin yog ib qho kev loj hlob hormone uas txhawb kev loj hlob ntawm txhua yam ntaub so ntswg ntawm lub cev.
Hormones yog cov tshuaj lom neeg cov cim qhia cov khoom uas nqa cov lus ntawm ntau qhov chaw ntawm lub cev. Lawv tsuas yog secreted los ntawm cov qog endocrine mus rau hauv cov hlab ntsha thiab thauj los ntawm kev ncig. Cov tshuaj hormones no cuam tshuam cov txheej txheem ntawm tes nrog rau kev loj hlob thiab kev loj hlob, kev loj hlob thiab cov metabolism. Somatotropin yog qhov kev loj hlob hormone uas txhawb kev loj hlob ntawm yuav luag tag nrho cov ntaub so ntswg hauv peb lub cev. Ntawm qhov tod tes, somatostatin yog somatotropin inhibitory yam tseem ceeb lossis kev loj hlob hormone inhibiting hormone uas inhibits somatotropin secretion. Ob leeg somatotropin thiab somatostatin yog peptide hormones.
Somatostatin yog dab tsi?
Somatostatin yog peptide hormone hu ua kev loj hlob hormone inhibiting hormone. Hauv cov lus yooj yim, somatostatin yog somatotrophin tso tawm inhibiting yam. Yog li, lub luag haujlwm tseem ceeb ntawm somatostatin yog inhibition ntawm kev tso tawm ntawm kev loj hlob hormone (somatotropin) los ntawm cov hlwb somatotroph. Tsis tas li ntawd, nws inhibits kev tso tawm ntawm insulin, glucagon, thiab cov tshuaj hormones hauv plab. Nws kuj yog feem ntau inhibitory rau plab hnyuv motility thiab exocrine secretion. Tsis tas li ntawd, somatostatin tau tshaj tawm cov nyhuv anti-proliferative. Nws tseem muaj peev xwm txhawb nqa cellular apoptosis

Tsis tas li ntawd, cov tshuaj no tso tawm los ntawm cov hlwb neuroendocrine ntawm hypothalamus. Nws muaj nyob rau hauv nruab nrab thiab peripheral paj hlwb. Nws kuj tseem pom muaj nyob hauv D (δ) hlwb ntawm pancreatic islets thiab gastrointestinal ib ntsuj av. Raws li txoj cai, somatostatin yog peptide muaj li ntawm 14 amino acid molecule. Muaj ob hom somatostatin: somatostatin 14 thiab somatostatin 28.
Somatotropin yog dab tsi?
Somatotropin yog qhov kev loj hlob hormone secreted los ntawm pituitary caj pas, tshwj xeeb tshaj yog los ntawm anterior pituitary hlwb hu ua somatotrophs. Cov tshuaj no yog lub luag haujlwm rau kev loj hlob ntawm tag nrho cov ntaub so ntswg hauv peb lub cev. Nws tseem txhawb nqa kev tsim tawm ntawm tes thiab rov tsim dua tshiab ntawm tes. Somatotropin ua nws txoj haujlwm los ntawm kev txhawb nqa cov protein synthesis thiab ua kom muaj roj ntau ntxiv los muab lub zog tsim nyog rau kev loj hlob ntawm cov ntaub so ntswg. Raws li txoj cai, somatotropin yog peptide tsim los ntawm 191 amino acids molecule.
Daim duab 02: Somatotropin
Kev loj hlob hormone-tso cov tshuaj hormones txhawb kev tso tawm ntawm somatotropin, thiab lub sijhawm no, somatostatin inhibits qhov tso tawm ntawm somatotropin. Somatotropin deficiency ua rau luv luv stature thiab dwarfism. Yog li, nws tuaj yeem kho tau los ntawm kev txhaj tshuaj uas muaj cov tshuaj hormones loj hlob. Ntawm qhov tod tes, ntau tshaj somatotropin ntau lawm yog teeb meem, thiab nws tuaj yeem ua rau cov qog loj hlob hauv somatotroph hlwb ntawm cov qog pituitary.
Dab tsi yog qhov zoo sib xws ntawm Somatostatin thiab Somatotropin?
- Ob leeg somatostatin thiab somatotropin yog peptide cov tshuaj hormones tsim los ntawm cov amino acid molecules.
- Somatostatin inhibits qhov tso tawm ntawm somatotropin.
- Ntxiv mus, ob qho tib si tso tawm los ntawm ob lub qog endocrine sib txawv hauv peb lub hlwb.
Qhov txawv ntawm Somatostatin thiab Somatotropin yog dab tsi?
Somatostatin yog peptide hormone uas ua haujlwm raws li kev loj hlob hormone inhibiting hormone. Lub caij no, somatotropin yog tib neeg kev loj hlob hormone uas txhawb kev loj hlob ntawm tag nrho cov ntaub so ntswg ntawm lub cev. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm somatostatin thiab somatotropin.
Ntxiv mus, somatostatin yog zais los ntawm hypothalamus thaum somatotropin yog zais los ntawm lub caj pas pituitary. Yog li, qhov no kuj yog qhov sib txawv ntawm somatostatin thiab somatotropin. Tsis tas li ntawd, somatostatin yog tsim los ntawm 14 thiab 28 amino acid molecules, thaum somatotropin yog tsim los ntawm 191 amino acid molecules.
Summary – Somatostatin vs Somatotropin
Somatostatin yog ib qho tshuaj tiv thaiv kab mob. Nws tseem hu ua qhov kev loj hlob hormone inhibiting hormone lossis somatotropin tso tawm inhibitory yam. Raws li lub npe qhia, somatostatin inhibits kev tso tawm ntawm somatotropin. Hauv qhov sib piv, somatotropin yog tib neeg txoj kev loj hlob hormone secreted los ntawm somatotrophs ntawm lub anterior pituitary caj pas. Nws yog peptide hormone uas yog lub luag haujlwm rau kev loj hlob ntawm tag nrho cov ntaub so ntswg ntawm peb lub cev. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm somatostatin thiab somatotropin.
