Descripción

Application

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.[1] 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.[2]

Biochem/physiol Actions

La L-tiroxina (T₄) y la triyodo-L-tironina (T₃) son hormonas que contienen yodo producidas a partir de la tiroglobulina en las células foliculares tiroideas. La estimulación de la tasa metabólica y la regulación del crecimiento y el desarrollo por esas hormonas parece deberse a sus efectos sobre la transcripción del ADN y, por tanto, la síntesis de proteínas.

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.[3]

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Preparation Note

L-Thyroxine dissolves in 4M ammonium hydroxide in Methanol at 50 mg/ml to yield a clear to hazy yellow to dark yellow solution.
