As a leading H-3-Iodo-Tyr-Oh supplier, we deliver high-quality products across diverse grades to meet evolving needs, empowering global customers with safe, efficient, and compliant chemical solutions.

What is the chemical structure of H-3-iodo-tyr-oh?
"H-3-iodo-tyr-oh" is the expression of chemical nomenclature, and the corresponding chemical structure refers to 3-iodo-tyrosine. It is a class of tyrosine derivatives. In its structure, iodine atoms are introduced at the third position of the tyrosine benzene ring.
Tyrosine is an α-amino acid with important biological functions. Its chemical structure contains amino (-NH ²), carboxyl (-COOH) and side chain aromatic ring structure. In 3-iodo-tyrosine, iodine atoms are added at specific positions in the tyrosine benzene ring, and this change affects its physical, chemical and biological properties.
From the perspective of chemical structure, its main chain is composed of amino, carboxyl and α-carbon atoms, and the side chain is a benzene ring connected to a hydroxyl group (-OH), and there is iodine atom substitution at the 3 position of the benzene ring. The introduction of this iodine atom may change the polarity, steric resistance and electron cloud distribution of the molecule, which in turn affects the way the compound interacts with other molecules. For example, the relatively large atomic radius of the iodine atom, or the spatial effect in the interaction between molecules; the electronegativity of iodine also affects the electron cloud density of the benzene ring, which plays an role in the reactivity and stability of the compound.
In biological systems, 3-iodine-tyrosine may participate in specific biochemical reactions. During the synthesis of thyroid hormone, the tyrosine residues contained in thyroglobulin will be iodized to produce 3-iodine-tyrosine and other iodized tyrosine intermediates. These intermediates are subsequently coupled to form biologically active thyroid hormones, which are of great significance for maintaining the normal physiological functions of the body, such as metabolism, growth and development.
What are the main uses of H-3-iodo-tyr-oh?
H-3-iodo-tyr-oh, or 3-iodine tyrosine, has important uses in medicine, biochemical research and other fields.
In the field of medicine, it plays a key role in the research of thyroid-related diseases and the development of therapeutic drugs. The thyroid gland uses iodine to synthesize thyroid hormones, and 3-iodine tyrosine is an important intermediate in thyroid hormone biosynthesis. Thyroid diseases such as hyperthyroidism or hypothyroidism are related to abnormal thyroid hormone synthesis and secretion. By studying the metabolic process of 3-iodine tyrosine, we can deeply understand the mechanism of thyroid hormone synthesis, provide a basis for the development of targeted therapeutic drugs, and help to explore new therapies for regulating thyroid hormone levels.
In biochemical research, 3-iodine tyrosine is widely used as a marker. Due to its unique physical and chemical properties, radioactive iodine can be used to label 3-iodine tyrosine to track the metabolism and transport pathways of proteins, peptides and other biomolecules in organisms. By detecting the radioactivity of the marker, researchers can clearly grasp the whereabouts of biomolecules in the body, and gain insight into complex physiological and pathological processes in organisms, such as protein synthesis, transportation and metabolic regulation mechanisms, providing powerful tools for basic research in life sciences.
In addition, 3-iodine tyrosine has also emerged in the research of cosmetic raw materials. Due to its unique biochemical properties, it may have a positive impact on skin physiological functions, such as regulating skin cell metabolism and promoting collagen synthesis, providing a potential direction for the development of new functional cosmetics, and is expected to assist in the development of high-end cosmetics with anti-wrinkle, whitening and other effects.
What are the synthesis methods of H-3-iodo-tyr-oh?
H-3-iodo-tyr-oh is the synthesis method of 3-iodo-tyrosine. Let me explain in detail.
First, tyrosine is used as the starting material. In the tyrosine molecule, the hydrogen atom of the phenolic hydroxyl ortho-site has a certain activity. Tyrosine can be placed in a suitable reaction system, with an iodine source (such as iodine elemental substance combined with an appropriate oxidant, such as hydrogen peroxide and iodine elemental compound), under mild reaction conditions, so that iodine atoms selectively replace hydrogen atoms of the phenolic hydroxyl ortho-site. This process requires fine control of the reaction temperature, time and the proportion of reactants. If the temperature is too high, it may cause excessive iodization or other side reactions; if the temperature is too low, the reaction rate will be Time control is also critical. If the reaction is too short, it may be incomplete, and if it is too long, it may cause unnecessary side reactions.
Second, organometallic catalysis can be used. Select specific metal catalysts, such as palladium, copper and other complexes, which can effectively promote the coupling reaction of iodine atoms and tyrosine. Such methods often have high selectivity and efficiency. However, the choice and dosage of metal catalysts are extremely important, and different catalysts have a significant impact on the reaction path and product yield. At the same time, the nature of the reaction solvent needs to be considered, because it has an effect on both catalyst activity and substrate solubility.
Third, biosynthetic pathways can also be used. Some microorganisms or enzyme systems have the ability to catalyze tyrosine iodization. By screening specific microorganisms, culturing and optimizing their culture conditions, the synthesis of 3-iodine tyrosine is achieved by using the enzyme system in microorganisms. This method is green and environmentally friendly, with good selectivity, but requires in-depth understanding of microbial culture and enzyme activity regulation. Culture conditions such as medium composition, pH, temperature, ventilation, etc. all affect microbial growth and enzyme activity, and then affect product synthesis.
How stable is H-3-iodo-tyr-oh?
H-3-iodo-tyr-oh, this is an organic compound, which can be called "3-iodine tyrosine" in Chinese. Its stability is related to many aspects, let me explain them one by one.
Structurally, there are iodine atoms, hydroxyl groups and amino groups attached to the benzene ring. Iodine atoms have a large atomic radius and electronegativity, and they are connected to the benzene ring. Due to the induction effect, the distribution of electron clouds in the benzene ring can be affected. This affects or alters the stability of the benzene ring, and also acts on other groups connected to it. Hydroxyl and amino groups are both active groups. Hydroxyl groups can form hydrogen bonds and build hydrogen bond networks between molecules or within molecules, which has a great impact on the stability of compounds. If an intramolecular hydrogen bond is formed, the molecular structure can be more compact and the stability can be enhanced; if it is an intermolecular hydrogen bond, it may affect the properties of its aggregate state.
Re-discussion of the chemical environment, in an acidic environment, the amino group or protonation changes the molecular charge distribution and polarity, which in turn affects the stability. In an alkaline environment, the hydroxyl group or deprotonation will also change the molecular properties. In case of an oxidizing agent, the iodine atom may be oxidized, resulting in structural changes and impaired stability.
Temperature is also a key factor. When the temperature increases, the molecular thermal motion intensifies, and the vibration of each atom in the molecule increases. If the energy is high enough, it may cause chemical breaking of the bond, and the stability decreases. In a low temperature environment, the molecular thermal motion slow
Light also has an effect. The light energy of a specific wavelength may be absorbed by the molecule, triggering electronic transitions and promoting chemical reactions, such as photolysis, breaking the original chemical bonds and reducing stability.
The properties of solvents are also not to be underestimated. Different solvents and solutes have different forces between molecules. Polar solvents or polar H-3-iodo-tyr-oh molecules form strong interactions, changing their molecular conformation and stability. Nonpolar solvents have weaker interactions with them and have different effects.
To sum up, the stability of H-3-iodo-tyr-oh is affected by many factors such as its own structure, chemical environment, temperature, light and solvent, and needs to be fully considered.
What is the mechanism of action of H-3-iodo-tyr-oh in living organisms?
H-3-iodo-tyr-oh has a complex and delicate mechanism of action in living organisms, which is related to many physiological and biochemical processes.
Br > Bearing the brunt, H-3-iodo-tyr-oh plays a crucial role in the synthesis of thyroid hormones. In the thyroid gland, after iodine ions are ingested, they are oxidized and combined with tyrosine residues on thyroglobulin to generate H-3-iodo-tyr-oh. This is a key step in the initiation of thyroid hormone synthesis. Subsequently, two molecules of H-3-iodotyrosine are coupled to generate thyroxine (T4); one molecule of H-3-iodotyrosine is coupled to one molecule of iodotyrosine to generate triiodothyronine (T3). As key hormones secreted by the thyroid gland, T4 and T3 have a profound impact on the growth and development of the body and the regulation of metabolism. It can act on many tissue cells in the body, regulate the rate of oxidative metabolism of cells, and affect the metabolic processes of proteins, carbohydrates and lipids, so as to maintain the body's energy balance and internal environment stability.
Furthermore, in the nervous system, H-3-iodotyrosine may also play a certain role. Although the specific mechanism is not fully understood, some studies have speculated that it may be related to the synthesis, release and regulation of neurotransmitters. In the nervous system, the synthesis of many neurotransmitters depends on the transformation of specific amino acids and their derivatives. H-3-iodine tyrosine, as an iodine derivative of tyrosine, may participate in the regulation of some neurotransmitter synthesis pathways, affecting neural signal transmission, which in turn affects neural function and behavioral performance.
In addition, in the field of immunomodulation, H-3-iodine tyrosine may have a potential role. The immune response of organisms is complex, and many cells and molecules are involved. Studies have shown that certain iodine-containing compounds can affect the activity and function of immune cells. H-3-iodine tyrosine may affect the expression of receptors on the surface of immune cells, cytokine secretion, etc., regulate the intensity and direction of immune response, help the body resist the invasion of pathogens, and maintain immune balance.
In summary, H-3-iodine tyrosine plays an important role in many key physiological processes such as hormone synthesis, neuroregulation, and immune regulation in vivo. Its subtle mechanism of action remains to be further explored and revealed by scientific researchers.
