Thyroglobulin

Thyroglobulin is a protein that is synthesized by thyroid cells (thyrocytes). After synthesis, it is released into the cavity of the thyroid follicle, where it undergoes the process of iodination. Then the colloid containing thyroglobulin enters back into thyrocytes, where it is broken down in lysosomes to release thyroid hormones - thyroxine and triiodothyronine. Thus, thyroglobulin plays an important role in the synthesis and secretion of these hormones.

Thyroglobin is a key protein in the structure of the thyroid gland. It ensures the correct functioning of the follicles. In addition to hormone synthesis, the main function of TSH is to participate in gene regulation.

Thyroxine (T4) and triiodothyronine (T3) are active substances created in the follicles of the thyroid gland by cells united in special follicle nuclei. There is also an inactive form of the hormone - iodothyroxine. This is the largest proportion of the total TSH. Further, when all parts of the molecule become active, with the exception of iodothyroxines, the latter dissolve. After that they change
