💡 Commercial Applications
Isopentenyl pyrophosphate is a key precursor in the biosynthesis of terpenes, which are natural compounds widely used in the fragrance industry. It is commonly employed in the production of perfumes, flavorings, and various cosmetic products due to its unique scent properties. The compound’s ability to serve as a building block for terpenes makes it valuable in the commercial sector for creating a wide range of aromatic products.
In the pharmaceutical industry, Isopentenyl pyrophosphate plays a crucial role in the production of bisphosphonates, a class of drugs used to treat bone-related disorders such as osteoporosis and Paget’s disease. By inhibiting bone resorption, bisphosphonates help to increase bone density and reduce the risk of fractures. Isopentenyl pyrophosphate is a key component in the synthesis of these drugs, making it indispensable in the production of medications that promote skeletal health.
⚗️ Chemical & Physical Properties
Isopentenyl pyrophosphate is a colorless liquid with a characteristic odor reminiscent of turpentine. It is commonly used in the biosynthesis of terpenes and other natural products.
The molar mass of Isopentenyl pyrophosphate is approximately 222.07 g/mol, with a density of about 1.19 g/cm3. This places it in the same range as common household items such as ethanol (molar mass 46.07 g/mol, density 0.789 g/cm3) and glycerol (molar mass 92.09 g/mol, density 1.261 g/cm3).
Isopentenyl pyrophosphate has a melting point of around 43-47°C and a boiling point of approximately 115-120°C. These values are notably higher than those of common household items like water (melting point 0°C, boiling point 100°C) and ethanol (melting point -114.1°C, boiling point 78.37°C).
Isopentenyl pyrophosphate is sparingly soluble in water and exhibits low viscosity. This contrasts with common household items like salt (high solubility in water) and honey (high viscosity).
🏭 Production & Procurement
Isopentenyl pyrophosphate is produced through the mevalonate pathway, a metabolic pathway that occurs in the cytoplasm of cells. This pathway involves a series of enzymatic reactions that convert acetyl-CoA into Isopentenyl pyrophosphate, a building block for the biosynthesis of isoprenoids.
Isopentenyl pyrophosphate can be procured through chemical synthesis or extraction from natural sources such as plants or microorganisms.
