Thyronamine refers both to a molecule, and to derivatives of that molecule: a family of decarboxylated
Decarboxylation is a chemical reaction that releases carbon dioxide . Usually, decarboxylation refers to a reaction of carboxylic acids, removing a carbon atom from a carbon chain. The reverse process, which is the first chemical step in photosynthesis, is called carbonation, the addition of CO2 to...

 and deiodinated
Iodine is a chemical element with the symbol I and atomic number 53. The name is pronounced , , or . The name is from the , meaning violet or purple, due to the color of elemental iodine vapor....

Metabolites are the intermediates and products of metabolism. The term metabolite is usually restricted to small molecules. A primary metabolite is directly involved in normal growth, development, and reproduction. Alcohol is an example of a primary metabolite produced in large-scale by industrial...

s of the thyroid hormone
Thyroid hormone
The thyroid hormones, thyroxine and triiodothyronine , are tyrosine-based hormones produced by the thyroid gland primarily responsible for regulation of metabolism. An important component in the synthesis of thyroid hormones is iodine. The major form of thyroid hormone in the blood is thyroxine ,...

s thyroxine
Thyroxine, or 3,5,3',5'-tetraiodothyronine , a form of thyroid hormones, is the major hormone secreted by the follicular cells of the thyroid gland.-Synthesis and regulation:...

 (T4) and 3,5,3'-triiodothyronine
Triiodothyronine, C15H12I3NO4, also known as T3, is a thyroid hormone. It affects almost every physiological process in the body, including growth and development, metabolism, body temperature, and heart rate....



The group includes:
  • Thyronamine (T0AM)
  • 3-Iodothyronamine
    3-Iodothyronamine is an endogenous thyronamine. T1AM is a high-affinity ligand for the trace amine-associated receptor TAAR1 , a G protein-coupled receptor...

     (T1AM), which is the most notable one as it is a trace amine
    Trace amine
    Trace amines are endogenous compounds structurally related to classical biogenic amines, such as catecholamines, serotonin and histamine. Trace amines include p-tyramine, β-phenylethylamine, tryptamine, octopamine, and 3-iodothyronamine, and are found in the nervous systems of animals from insects...

     found in the nervous system
    Nervous system
    The nervous system is an organ system containing a network of specialized cells called neurons that coordinate the actions of an animal and transmit signals between different parts of its body. In most animals the nervous system consists of two parts, central and peripheral. The central nervous...

    . It is a possible candidate for the natural ligand of the trace amine-associated receptor
    Trace amine-associated receptor
    Trace amine-associated receptors, abbreviated TAAR and otherwise known as trace amine receptors, abbreviated TAR or TA, are a class of G protein-coupled receptors identified in 2001....

     TAAR1 (TAR1), a G protein-coupled receptor
    G protein-coupled receptor
    G protein-coupled receptors , also known as seven-transmembrane domain receptors, 7TM receptors, heptahelical receptors, serpentine receptor, and G protein-linked receptors , comprise a large protein family of transmembrane receptors that sense molecules outside the cell and activate inside signal...

    Cell membrane
    The cell membrane or plasma membrane is a biological membrane that separates the interior of all cells from the outside environment. The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. It basically protects the cell...
