DETAILS

Description (English)

Biochem/physiol Actions
L-Thyroxine (T4) and triiodo-L-thyronine (T3) are iodine-containing hormones produced from thyroglobulin in the thyroid follicular cells. The stimulation of metabolic rate and regulation of growth and development by these hormones appear to be due to their effects on DNA transcription and, thus, protein synthesis.

Description (简体中文)

Biochem/physiol Actions
L甲状腺素 (T4) 和三碘代-L-甲状腺原氨酸 (T3) 为含碘激素，由甲状腺卵泡细胞中的甲状腺球蛋白制备。这些激素对代谢率的刺激以及对生长发展的调节似乎归因于它们对 DNA 转录的作用，进而影响蛋白质的合成。
