Hormones



  • Do t3 and t4(thyroxine) have same function in our body? Then why are two different hormones required? Please explain.



  • @anag
    The function of the thyroid gland is to take iodine, found in many foods, and convert it into thyroid hormones: thyroxine (T4) and triiodothyronine (T3). Thyroid cells are the only cells in the body which can absorb iodine. These cells combine iodine and the amino acid tyrosine to make T3 and T4.
    Triiodothyronine is a thyroid hormone that plays vital roles in the body's metabolic rate, heart and digestive functions, muscle control, brain development and function, and the maintenance of bones.
    T4 being the inactive form, and T3 being the active form of thyroid hormone. ... “The function of the thyroid gland is to take iodine, found in many foods, and convert it into thyroid hormones: thyroxine (T4) and triiodothyronine (T3).Thyroid cells are the only cells in the body which can absorb iodine.



  • @sunitasaxena thyroxine is the name of t4 whereas tri-iodothyronine is name of t3.

    Thyroxine is not t3, isn't it?

    My doubt is:"Do t3 and t4 have same function in our body? Then why are two different hormones required?" Please explain.
