define thyroxine in animals
Thyroxine is a hormone made in the thyroid gland for the regulation of metabolism, body heat production, blood pressure, and the normal development of the skeletal and nervous systems. Thyroxine is an amino acid-based hormone that targets the genes involved in the metabolism of glucose in the body. Iodine in the blood is a key component of making thyroxine, and if not enough iodine is present, it can lead to the development of abnormal growths called goiters.
