Thyroxine Function, Definition, Control And Chemical Formula

Thyroxine is the main hormone secreted in the blood stream by thyroid gland. It plays an important role in digestion, heart and muscle function, brain development and bone maintenance.

What is Thyroxine?
Thyroxine is the main hormone secreted in the blood stream by thyroid gland. It is an inactive form and most of these are actively converted into an active form called triiodothyronine by the organs such as the liver and kidneys. Thyroid hormones play an important role in regulating the body’s metabolic rate, heart and digestive function, muscle control, brain development and bone maintenance.

How is Thyroxine Controlled?
The production and release of thyroid hormone, thyroxacine and triiodothyronine is controlled by a feedback loop system, which involves the hypothalamus in the brain and pituitary and thyroid glands. The hypothalamus passes through thyrotropin-releasing hormone which, in turn, stimulates the pituitary gland to produce thyroid stimulating hormones. This hormone stimulates the production of thyroid hormones, thyroxine and triiodothyronine by thyroid gland.

This hormone production system is controlled by the feedback loop so that when the level of thyroid hormone (thyroxine and triiodothyronine) increases, they prevent the release of thyrotropin-releasing hormones and thyroid stimulating hormones. This system allows the body to maintain continuous levels of thyroid hormone in the body.

What if I Have too Much Thyroxine?
The release of excess thyroxine in the blood stream is known as thyrotoxicosis. This may be due to the hyperthyroidism of hyperthyroidism, such as swelling of the grave disease, thyroid or benign tumor. Thyrotoxicosis can be identified by a goiter, which is due to the expansion of the thyroid gland, due to the swelling of the neck. Other symptoms of thyrotoxicosis include heat, weight loss, increased appetite, increased bowel movement, irregular menstrual cycle, fast or irregular heartbeats, tilt, weariness, irritability, shivering, hair loss / loss and retrogression of the eyelids. ‘Stare’ ‘presence.

What if I Have Very Little Thyroxine?
Very low production of thyroxine by thyroid gland is known as hypothyroidism. This may be due to the use of autounein diseases, bad iodine intake or some medicines. Occasionally, the reason is unknown. Thyroid hormones are essential for physical and mental development, so hypothyroidism that is not treated during birth or during childhood can decrease mental disorder and reduce development.

Hypothyroidism in adults causes less metabolism. As a result, fatigue, intolerance of cold temperatures, low heart rate, weight gain, loss of appetite, poor memory, depression, muscle stiffness and low fertility may be. See the article on hypothyroidism for more information.

Chemical Formula of Thyroxine
Thyroxine, also called 3,5,3′,5′-tetraiodothyronine or T4, is one of the two major hormones secreted by thyroid gland (the second is triiodothyronine). The main function of thyroxine is to stimulate oxygen consumption and thus stimulate metabolism of all cells and tissues in the body. Thyroxine is produced by amino acid tyrosine by the molecular joint of iodine, while later the protein is associated with thyroglobulin. Excessive secretion of thyroxine in the body is known as hyperthyroidism, and secretion of its deficiency is called hypothyroidism. The chemical composition of thyroxine is
