The major form of thyroid hormone in the blood is thyroxine (T 4. One effect of administering the thyronamines is a severe drop in body temperature).Symbol: T 4. Also, thyroxin thahy- rok -sin /ark sn/ ( Show IPA ). 1915-20; thyr- ox- in(dol)e (orig. thought to be a chemical component) British Dictionary definitions for thyroxine Expand noun 1.
The interrelationships of thyroid and growth hormones: effect of growth hormone releasing hormone in. and increases the peripheral conversion of thyroxine to.The hormone, which excites the nervous system and leads to increased activity of the endocrine system, remains active in the body for more than a month. Thyroxine plays an important role in childhood development, metabolism regulation, and breaking down fats and proteins.
Nutritional facts and information on hormone thyroxine, with reviews on the hormonal health benefits, biological functions, and side effects of thyroxine.Thyroxine is necessary for normal neural development and normal cellular metabolism. Thyroxine increases the metabolic rate of most cells. In amphibians it is responsible for metamorphosis. Thyroxine increases the number and activity of mitochondria in cells by binding to the cells' DNA, increasing the basal metabolic rate.
Noun 1. Biochemistry. the thyroid gland hormone that regulates the metabolic rate of the body. 2. Pharmacology. a commercial form of this compound, obtained from the thyroid glands of animals or synthesized, used in the treatment of hypothyroidism.Thyroxine medications which include combinations of levothyroxine, and/or liothronine, or dextrothyroxine, or thyroid, and one or more iodine salts, or iodine donor compounds are described, which produce a stable thyroxine medication, with a long shelf life.
Children with thyroid hormone deficiency are easily treated by supplementation with synthetic thyroxine, which enables them to grow and develop normally. Synthetically prepared thyroxine is used clinically in the treatment of thyroid gland deficiency diseases in adults and in the treatment of cretinism in children.Thyroxine is the main hormone secreted into the bloodstream. thyroxin. What is thyroxine?. Too little production of thyroxine by the thyroid gland is known as.
Thyroxine is taken to replace the deficiency which exists in such situations and therefore to restore normal metabolic activity. In humans, children born with thyroid hormone deficiency will not grow well, and brain development can be severely impaired, in the condition referred to as cretinism.Not all side effects for L Thyroxine Roche may be reported. A study evaluated the effect of long-term thyroid hormone therapy on bone mineral density in 196.
Low Thyroxine Hormone Level. Persons who have low thyroxine level or hypothyroidism are often prescribed with synthetic medications called thyroxine or.Chemical name: tetra-iodothyronine; formula: C 15 H 11 I 4 NO 4 C19: from thyro- oxy- -ine Word Origin and History for thyroxine Expand n. from thyro-, comb. form of thyroid, oxy- indole chemical suffix -ine (2).
Thyroxine enters into the bloodstream complexed to another protein, plasma globulin. The sole function of the thyroid is to make thyroid hormone. Thyroxine and tri-iodothyronine are necessary for normal brain development and for normal metabolic rates.The thyroid gland is composed of spherical follicles that selectively absorb iodine from the bloodstream and concentrate it for production of thyroid hormones. Thyroxine is stored in the follicle stems between thyroid cells.
The principal hormone produced by the thyroid gland: it increases the metabolic rate of tissues and also controls growth, as in amphibian metamorphosis. It can be synthesized or extracted from the thyroid glands of animals and used to treat hypothyroidism.Thyroid hormone is used in two situations:. Pure, synthetic thyroxine (T4) works in the same way as a patients own thyroid hormone would.
Thyroxine is an iodine -containing hormone, produced by attaching iodine atoms to the ring structures of tyrosine molecules. Thyroxine forms by combining the amino acid tyrosine with iodine. Thyroxine is produced by follicular cells of the thyroid gland.Thyroxine in Science Expand thyroxine (th-rk'sn -sn) An iodine-containing hormone secreted by the thyroid gland that increases the rate of cell metabolism and regulates growth. Thyroxine can also be made synthetically for treatment of hypothyroidism.
Biochemistry. the thyroid gland hormone that regulates the metabolic rate of the body. See more. Thyroxine can also be made synthetically for treatment of.Thyroxine releases fats from most fat cells, increases metabolism by influencing mitochondria, and in lower vertebrates induces metamorphosis. Every cell in the body depends upon thyroid hormones for regulation of their metabolism.
Thyroxine is the main hormone produced by the thyroid gland. Hypothyroidism is the disease state caused by insufficient thyroid hormone by the thyroid gland. Hypothyroidism is the condition that results from under-production of thyroxine by the thyroid gland either because the gland is naturally underactive or because radioiodine therapy or surgery for an overactive gland.The thyroid hormones act on the body to increase the basal metabolic rate, affect protein synthesis and increase the body's sensitivity to catecholamines (such as adrenaline). Thyroxine causes an increase in the rate of carbohydrate metabolism and a rise in the rate of protein synthesis and breakdown.
