What is the difference between thyroxine and triodothyronine?
thyroxine and triodothyronine, or t 4 and t 3 are the main thyroid hormones and differ the amount produced as they are produced and their strength. They should also be noted that they have a great similarity; Thyroxine has the ability to transform into triodothyronine and should be considered as a precursor. In the end, it is t 3 , which has the greatest effect on most cells in the body, but there would be no t 4 , so they are vital hormones. Another way to compare these chemicals is the assessment of their benefits as prescription drugs. One clear difference between thyroxine and triodothyronine is recorded in how much of each of each thyroid gland. About 80% of the total production is thyroxine and only 20% is triodothyronine.
because t 3 affects most body cells, this production does not seem to be adequately for the task, especially because most hormone is bound to proteins and only a small amount is left on other cells in the bodiese. However, it is sufficient because it is also produced outside the thyroid gland. In some organs, as well as the liver, free thyroxin is deprived of one of the four atoms of iodine. The result is a new production of T 3 . In this process, it is easy to see the relationship of thyroxine and triodothyronine because t 4 is necessary to create the corresponding amounts of t 3
When this conversion is constantly repeated, more t 3 is produced and then can have a direct effect on different parts of the body. It helps to regulate calories, metabolism, temperature control and production of key neurotransmitters. It affects a number of processes in the proper supply of trieiodothyronine and has an impact on physical and mental health. Comparison T 4 is slightly less direct, but exists, but exists in a much stronger t 3 .
Sometimes patients who have low thyroid problems want directA comparison of different drugs containing thyroxine and triodothyronine. Until the mid -20th century, doctors did not know that T 4 was made to t 3 and often often prescribed both hormones. Because triodothyronin is much stronger, it can easily cause hyperthyroidism. As soon as the relationship between these two hormones was clearly determined, there was no point in prescribing both drugs.
At present, most doctors are only prescribed thyroxine because it will be made to t 3 . Patients sometimes do not tolerate thyroxine well and instead a case for prescribing much less triodothyronine is made. There is still some concern that t 3 generally causes people to have hypothyroidism for a few hours every day afterwards. There are also concerns about triodothyronine stability in the form of pills and in many cases doctors prefer to prescribe thyroxine.
