Iodinated thyroglobulin
WebHere the thyroglobulin and iodine combine to form iodinated thyroglobulin. Audio 6 Narrator: "In the second phase, follicular cells absorb iodinated thyroglobulin by endocytosis and lysosomal enzymes hydrolyze the thyroglobulin to produce T3 and T4, which are secreted into the bloodstream. WebDuring the incubation, initially dissociable thyroglobulin was gradually altered to 0.3 mM SDS-resistant species with increasing incorporation of iodine. Microsome-bound, poorly …
