deiodinaasit
Deiodinaasit are a family of enzymes that play a crucial role in thyroid hormone metabolism. These enzymes are responsible for catalyzing the removal of iodine atoms from thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3). This process is essential for regulating the biological activity of thyroid hormones.
There are three main types of deiodinases: type 1 (D1), type 2 (D2), and type 3 (D3).
The activity of deiodinases is tightly regulated by various factors, including thyroid hormone levels themselves, selenium,
