Receptors rau cov thyroid hormones yog cov tswv cuab ntawm tsev neeg loj ntawm cov receptors nuclear uas suav nrog cov tshuaj hormones steroid. Lawv ua haujlwm raws li cov tshuaj hormone-activated transcription yam thiab yog li ua los ntawm modulating noob qhia.
YPuas yog cov thyroid hormone yog steroid hormone?
Txawm hais tias steroid thiab thyroid hormones tsis yog cov txheej txheem lossis biosynthetically cuam tshuam, lub neej ntawm cov qauv rau lawv cov receptors txhawb cov lus pom zoo tias muaj cov noob loj loj ntawm cov noob uas nws cov khoom yog ligand-responsive transcription factor.
Qhov txawv ntawm steroid thiab thyroid hormones yog dab tsi?
Txhua cov tshuaj hormones steroid siv lawv qhov kev txiav txim los ntawm kev dhau los ntawm cov plasma membrane thiab khi rau intracellular receptors. Cov txheej txheem ntawm kev ua ntawm cov thyroid hormones yog similar; Lawv cuam tshuam nrog intracellular receptors.
YPuas yog cov thyroid hormone yog steroid lossis peptide?
Thyroid-stimulating hormone yog peptide hormone. Tyrosine derivatives yog hloov los ntawm cov molecules ntawm cov amino acid tyrosine, ua rau lawv polar. Cov thyroid hormones thiab epinephrine yog muab los ntawm tyrosine.
