The primary acid found in bones, according to the provided reference, is fumaric acid. However, the reference also notes that or-ketoglutaric acid is present in smaller amounts.
Acids in Bone
While bones are primarily known for their calcium and mineral content, they also contain several organic acids. The reference specifically identifies:
- Fumaric acid: This is present in fresh bone, although its exact percentage cannot be accurately measured using column chromatography.
- Or-ketoglutaric acid: Found in bone at lower concentrations than in the liver.
The reference highlights that fumaric acid and or-ketoglutaric acid are the only acids present in bone at smaller concentrations compared to the liver. It does not discuss other acids in bone.
Further Notes on Bone Acids
- The exact functions of these acids in bone are not detailed in the provided reference. However, organic acids can play roles in bone metabolism.
| Acid | Concentration | Comparison to Liver |
|---|---|---|
| Fumaric acid | Unknown | Lower |
| Or-ketoglutaric acid | Unknown | Lower |
It's important to note that while these acids are present, they are not the main structural components of bone. They play different roles that may relate to bone cell activity.
