Mineralisationsinhibitor

A mineralisation inhibitor is a substance that slows, prevents, or regulates the deposition of minerals or the formation of mineralized tissues. In different fields, inhibitors may act to limit unwanted mineral growth, or to modulate normal mineralization processes.

In biological systems, mineralisation inhibitors help control where and how minerals such as calcium phosphate are deposited. They play a role in bone and dental biology, as well as in soft tissues where unwanted calcification can occur. Natural inhibitors include small molecules like citrate and pyrophosphate, as well as larger proteins that interact with mineralizing surfaces. Pharmacological inhibitors, such as certain bisphosphonates, can reduce excessive mineralization or bone turnover in medical conditions like osteoporosis. Dysregulation of mineralisation inhibitors is linked to diseases such as vascular calcification and nephrocalcinosis.

In industrial and environmental contexts, mineralisation inhibitors are used to prevent scale formation and mineral deposits in water systems, oil pipelines, and heat exchangers. Agents such as phosphonates, polyphosphates, and polycarboxylates bind calcium or other ions, disrupt crystal growth, or modify pH to reduce precipitation. In construction and cement chemistry, inhibitors may limit efflorescence and unwanted mineral transport to surfaces.

Mechanisms include chelation of ions, inhibition of crystal nucleation and growth, and interference with crystal lattice formation. The choice of inhibitor depends on the specific mineral system, desired outcome, and compatibility with the surrounding matrix or biological tissue.
