C6H15O19P3

C6H15O19P3, also known as inositol hexakisphosphate (IP6), is a polyphosphate derivative of inositol, a cyclic alcohol with six hydroxyl groups. It is a significant molecule in cellular signaling and metabolism, particularly in the regulation of cellular processes such as cell division, gene expression, and membrane trafficking. IP6 is synthesized from inositol through a series of phosphorylation reactions, catalyzed by specific kinases. It is a water-soluble compound, making it readily available for intracellular signaling. IP6 can be further metabolized to other polyphosphates, such as inositol pentakisphosphate (IP5) and inositol tetrakisphosphate (IP4), which also play crucial roles in cellular signaling. The structure of IP6 consists of a six-membered ring with six phosphate groups attached to the hydroxyl groups, resulting in a highly charged molecule. This polyanionic nature allows IP6 to interact with various proteins and other molecules, facilitating its role in cellular signaling. IP6 is found in various organisms, including plants, animals, and microorganisms, highlighting its ubiquitous nature and importance in biological systems.
