99% Thyroid Hormone T4 Raw Powder L-Thyroxine to Treat Obesity
Assay: 99% min. USP30
Character: White Crystalline Solid
L-thyroxine is the major hormone derived from the thyroid gland. Thyroxine is synthesized via the
iodination of tyrosines (MONOIODOTYROSINE) and the coupling of iodotyrosines (DIIODOTYROSINE) in
the THYROGLOBULIN. Thyroxine is released from thyroglobulin by proteolysis and secreted into the
blood. Thyroxine is peripherally deiodinated to form TRIIODOTHYRONINE which exerts a broad spectrum of stimulatory effects on cell metabolism.
Levothyroxine is a synthetic levoisomer of thyroxine (T4), similar to the endogenous hormone produced
by the thyroid gland. Thyroxine is de-iodinated to form triiodothyronine (T3) in the peripheral tissues. T3
enters the cell and binds to nuclear thyroid hormone receptors, and the hormone-receptor complex in turn triggers gene expression and produces proteins required in the regulation of cellular respiration,
thermogenesis, cellular growth and differentiation, and metabolism of proteins, carbohydrates and lipids.
T4 and T3 also possess cardiac stimulatory effect.
L-Thyroxine is an iodine containing hormone produced from thyroglobulin in the thyroid follicular cells. L-
Thyroxine reduces total cholesterol level, low-density lipoprotein cholesterol as well as waist to hip ratio in
subclinical hypothyroidism pateints. Hence, facilitates in improving cardiovascular risk factor as well as can enhance symptoms of tiredness
L-Thyroxine was used to study the light-induced hormone conversion of T4 to T3 in regulation of
photoperiodic response of gonads in Japanese quail. The product was used as a test compound for
studying the impact of numerous hormones on the surface morphology of rat testicular cells in culture
