Calcium Phosphate is the salt found in maximum quantity in bones.

The bones in the human body consist of a complex combination of minerals, proteins, and other organic compounds. Among these minerals, calcium phosphate is the most abundant salt found in bones.

Importance of Calcium Phosphate in Bones:
- Structural Component: Calcium phosphate provides strength and rigidity to the bones, making them strong enough to support the body and protect internal organs.
- Mineral Reservoir: Bones act as a storage site for calcium and phosphate, which are essential minerals for various bodily functions. When the body needs calcium or phosphate for other processes, it can be released from the bones into the bloodstream.
- Bone Formation and Remodeling: Calcium phosphate plays a crucial role in bone formation and remodeling. During bone development and growth, calcium phosphate combines with collagen to form hydroxyapatite crystals, which make up the mineralized matrix of the bone. This process is essential for bone mineralization and the overall integrity of the skeletal system.
- Regulation of Calcium Levels: Calcium phosphate in bones helps regulate the levels of calcium in the body. When blood calcium levels are low, parathyroid hormone stimulates the release of calcium from the bones into the bloodstream, maintaining calcium homeostasis.

Comparison with other Salts:
- Calcium Carbonate: While calcium carbonate is also present in bones, it is found in relatively smaller quantities compared to calcium phosphate. Calcium carbonate contributes to the compressive strength of bones and is primarily found in the mineralized matrix.
- Magnesium Chloride: Magnesium chloride is not a major component of bone composition. It plays a role in various biochemical reactions in the body but is not present in significant quantities in bones.
- Sodium Chloride: Sodium chloride, or common table salt, is not a component of bone composition. It is primarily involved in maintaining fluid balance and is not directly related to bone structure.

Hence, the correct answer is option 'A' - Calcium Phosphate.

Which salt is found in maximum quantity in bones?a)Calcium Phosphateb)...
  • Skeleton is a structure of bones that is hard and gives movement to many parts of the body.
  • These give support to the body.
  • The main parts of the skeleton are:
    • Skull - box giving protection to the human mind which starts from
  • brain and ends at the spinal cord.
    • Ribs - these cover lungs and heart,
    • Bones of shoulder and hips
  • The total number of bones in our body is 206.
Explanation:
  • The three major components of bone are minerals, cells, and an organic extra-cellular matrix i.e. collagen fibers.
  • The main bulk of bone is approximately 70% mineral and 30% organic components by weight.
  • The mineral salt of bone is mainly calcium phosphate.
​​Thus, calcium phosphate salt is found in maximum quantity in bones.
