Thyroid Hormone Triiodothyronine

An informative article on: Thyroid Hormone Triiodothyronine.

The Thyroid Hormone Triiodothyronine, also referred to as T3 has an import is role in our chemical makeup and it's is largely responsible for nearly every physiological process in our bodies. Our metabolism, growth, and overall physical development are affected by T3. Moreover, this hormone also has a direct impact on our bones and central nervous system including neurotransmitters and our bone’s growth rate. It also has a direct impact on the development of embryos and fetuses.

An Explanation of Thyroid Hormone Triiodothyronine

Of all of the thyroid hormones that are produced, almost 20% of these hormones are T3. The additional 80% is taken up by the T4 hormone. The effects of T3 are also almost 4 times greater than other hormones produced in the thyroid. T3 is produced when the iodine atom is removed from the carbon atom number five in the T4 outer layer. Basically, Triiodothyronine is roughly 1/40 of the hormones created by your thyroid. Its life span is only 2 ½ days compared to the life span the T4 hormone which is closer to 6 1/2 days.

The Production and Location of Triiodothyronine

T3 and T4 are bound to three types of proteins in our plasma; both of these hormones are bound by serum albumin due to its high capacity. When our pituitary gland releases thyroid stimulating hormones (TSH), T3 will then become activated. If there is a large activation of T3 and T4 in our blood plasma, the production of the Thyroid Stimulating Hormone will be decreased. Thus, when T3 and T4 are decreased, TSH will then increase as well. Therefore, our body has set up a feedback control system to ensure that the hormones produced by our thyroid are regulated in our blood stream.

The Purpose of Thyroid Hormone Triiodothyronine

The Thyroid Hormone Triiodothyronine is needed to increase our body's oxygen and energy intake. The energy intake, or minimal caloric requirement, is needed by our bodies to sustain life during an individual’s period of rest. Moreover, T3 is a very powerful hormone that is needed for every major organ and tissue in the body except for your spleen and testis. The T4 hormone, that is less active, is simply waiting to be turned into T3 when the body needs it.

The Effects that Thyroid Hormone Triiodothyronine Has on Other Chemicals in the Body

The body may go into negative ion balance if T3 increases the rate of protein synthesis, and protein degradation exceeds the rate of protein synthesis due to its own increase by T3. Moreover, Triiodothyronine has a direct impact on the metabolism of glucose. Furthermore, the effects of insulin are also potentiated. T3 will also affect the cardiovascular system by increasing heart rate and forcing our heart to contract. Finally, T3 is also known to possibly reduce serotonin in the brain.
