Metabolite Identification
Common NameTriiodothyronine
DescriptionLiothyronine, also known as T3 or liotironina, belongs to the class of organic compounds known as phenylalanine and derivatives. Phenylalanine and derivatives are compounds containing phenylalanine or a derivative thereof resulting from reaction of phenylalanine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. An iodothyronine compound having iodo substituents at the 3-, 3'- and 5-positions. The sodium salt is used in the treatment of hypothyroidism. Liothyronine is a very strong basic compound (based on its pKa). Its metabolic activity is about 3 to 5 times that of L-thyroxine. Liothyronine exists in all living organisms, ranging from bacteria to humans. In humans, liothyronine is involved in thyroid hormone synthesis. Liothyronine is a potentially toxic compound. Although some is produced in the thyroid, most of the 3,3',5-triiodo-L-thyronine in the body is generated by mono-deiodination of L-thyroxine in the peripheral tissues.
