Is Hydroxyapatite Organic or Inorganic?

COMPOSITION OF BONE
Bone is a composite material consisting of both inorganic and organic components [1,2,12]. The inorganic component is primarily crystalline hydroxyapatite: [Ca3(PO4)2]3Ca(OH)2. The organic component of bone comprises more than 30 proteins with type I collagen being the most abundant (>90%) [1,2,12].

What are the organic and inorganic components of bone matrix?

Bone matrix (also known as osteoid) consists of about 33% organic matter (mostly Type I collagen) and 67% inorganic matter (calcium phosphate, mostly hydroxyapatite crystals).
