The Importance Of Thyroid Hormones
Thyroid hormones is a result to the release of thyroid stimulating hormones by the pituitary gland. The thyroid, a butterfly shaped gland found in the lower part of the neck produces two types of tyrosine based hormones. These are thyroxine (T4) and triiodothyronine (T3). T4 and T3 ratio that is released to the blood is approximately around 20 to 1. Thyroid hormones are the only major biochemical molecules that incorporates iodine which is present in all chordate animals. Iodine is the key component in the synthesis of thyroid hormones, and the lack can lead to the thyroid condition hypothyroidism.
