What three substances compose animal skeleton?

Animal skeletons are primarily composed of three main substances:

1. Calcium Phosphate (Hydroxyapatite):

- Calcium phosphate, in the form of hydroxyapatite, is the primary mineral component of animal bones and teeth.

- It provides rigidity and strength to the skeletal structure, making it hard and resistant to deformation.

2. Collagen:

- Collagen is a fibrous protein that forms the organic matrix or framework within which calcium phosphate is deposited.

- It provides flexibility and tensile strength to the skeleton.

3. Water:

- Water is also a crucial component of the skeleton.

- It acts as a medium for transporting minerals and nutrients and contributes to the overall flexibility and resilience of skeletal structures.
