Cov thyroid hormones yog muab los ntawm cov amino acid tyrosine thiab yog synthesized los ntawm sequential iodination ntawm tyrosine phenol rings Ua ntej, iodine ntxiv rau phenol nplhaib meta txoj haujlwm, ua rau monoiodotyrosine. Yog hais tias ib qhov chaw yog iodinated los yog diiodotyrosine yog tias ob qhov chaw yog iodinated.
Dab tsi yog qhov tseem ceeb hauv kev tsim cov thyroid hormone?
Rau cov thyroid hormone synthesis, txaus txaus ntawm cov thyroid caj pas nrog tseem ceeb micronutrients xws li iodine thiab selenium yog qhov tseem ceeb.
Qhov kev sib txuas ntawm cov thyroid hormone nyob qhov twg?
Thyroid hormone biosynthesis tshwm sim ntawm qhov chaw apical ntawm polarized thyroid follicular cells thiab xav tau txoj hauv kev sib xyaw ua ke uas suav nrog cov khoom thauj khoom, enzymes thiab thyroglobulin nrog rau kev noj zaub mov txaus iodide (Fig. 2).
Cov hlwb twg tsim cov thyroid hormones?
Cov thyroid hormones (T4 thiab T3) yog tsim los ntawm cov hlwb follicular ntawm cov thyroid caj pasthiab raug tswj los ntawm cov thyroid-stimulating hormone secreted los ntawm lub caj pas anterior pituitary.
Lub luag haujlwm tseem ceeb ntawm cov thyroid hormone yog dab tsi?
Cov thyroid hormones cuam tshuam rau txhua lub cell thiab tag nrho cov kabmob ntawm lub cev. Lawv: Tswj tus nqi uas calories hlawv, cuam tshuam qhov hnyav lossis hnyav nce. Ua kom qeeb lossis ua kom lub plawv dhia nrawm.

Ntawm no, los ntawm cov kev xaiv muab Nylon-6, 6 yog cov polymer uas muaj kev sib txuas ntawm amide. Yog li, nylons tseem hu ua polyamides vim lawv cov yam ntxwv amide pawg hauv cov pob txha caj qaum. Amide pawg nyob rau hauv nylon molecules yog heev polar, thiab tsim hydrogen bonding ib leeg .
Puas kev sib txuas lus tsis zoo kuj yog ib qho khoom ntawm kev sib txuas lus?
Kev sib txuas lus tsis zoo ("mis" + "kev sib txuas lus") txhais tau tias yog tsis ua tiav kev sib txuas lus kom txaus thiab zoo Nws yog ib hom kev sib txuas lus teeb meem. … Hom kev sib txuas lus tsis zoo tam sim no tuaj yeem raug cais raws li lub hauv paus ntawm kev tsis sib haum xeeb txog txoj cai sib txuas lus .
Leej twg tsim tus qauv kev sib txuas lus ntawm kev sib txuas lus?
Tus qauv kev sib txuas lus ntawm kev sib txuas lus tsim los ntawm Wilbur Schramm ua raws li tus qauv linear. Schramm ntxiv peb yam tseem ceeb rau Shannon thiab Weaver qauv. Ua ntej, Schramm tau txheeb xyuas ob txheej txheem ntawm kev sib txuas lus:
Nyob rau hauv ib qho kev tsis sib haum xeeb pn kev sib tshuam cov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
Nyob rau hauv qhov tsis ncaj ncees PN-kho qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog zero, vim tias sib npaug tab sis cov neeg nqa khoom hla hla kev sib tshuam . Thaum pn kev sib tshuam tsis ncaj ncees qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
