Bone Mineral Matrix (Hydroxyapatite) (Hydroxyapatite)

Target
Hydroxyapatite
Molecular classification
Mineral, Inorganic Matrix, Calcium Phosphate
01

Overview

The bone mineral matrix, primarily composed of hydroxyapatite (Ca10(PO4)6(OH)2), is the inorganic component of bone that provides rigidity and strength. It serves as a reservoir for calcium and phosphate and is essential for bone remodeling and overall skeletal health. While it is not a direct therapeutic target, its formation and resorption are influenced by various drugs targeting bone metabolism. The matrix is a composite of hydroxyapatite nanocrystals embedded in a collagenous organic matrix.

Mechanism of action

Bisphosphonates bind to hydroxyapatite and inhibit osteoclast activity, reducing bone resorption.
