Q. Our bones & teeth are generally made of -
✅ Correct Answer: (A)
Tricalcium phosphate
Explanation:
Bones and teeth are primarily composed of calcium phosphate in the form of hydroxyapatite, which is a crystalline structure of tricalcium phosphate .
- Bones: Contain about 70% hydroxyapatite, giving them strength and rigidity.
- Teeth (Enamel & Dentin): Also have hydroxyapatite, but fluorapatite (fluoride-enriched hydroxyapatite) strengthens enamel and makes it more resistant to decay.
Thus, tricalcium phosphate is the main mineral in bones and teeth, making (A) Tricalcium phosphate the correct answer.
