Organic phosphorous distribution in chicken bone matrix

Non-collagenous, soluble proteins and collagen have been extracted quantitatively from freshly dissected chicken bone at 4 ûC in presence of protease inhibitors, and their content in organic phosphorus assayed. We found that non-collagenous proteins were not covalently bound to collagen in chicken bone, as in some calcified tissues. They represented 30 p. 100 of the organic matrix and bound 75 ...

Phosphoproteins of chicken bone matrix. Proof of synthesis in bone tissue.

Twelve-day-old embryonic chick mandibles were cultured in vitro for 6 days. Measurements of the weights of the explants, their mineral and protein components, and the EDTA-extractable proteins established that bone tissue synthesizes O-phosphoserine- and O-phosphothreonine-containing phosphoproteins which are similar to those present in embryonic and postnatal chicken bone matrix. The synthesis...

Characteristics of global organic matrix in normal and pimpled chicken eggshells.

The organic matrix from normal and pimpled calcified chicken eggshells were dissociated into acid-insoluble, water-insoluble, and facultative-soluble (both acid- and water-soluble) components, to understand the influence of shell matrix on eggshell qualities. A linear correlation was shown among these 3 matrix components in normal eggshells but was not observed in pimpled eggshells. In pimpled ...

Altered distribution of bone matrix proteins and defective bone mineralization in klotho-deficient mice.

In an attempt to identify the histological properties of the klotho-deficient (kl/kl) bone matrix, bone mineralization and the localization of Ca(2+)-binding bone matrix proteins - osteocalcin, dentin matrix protein-1 (DMP-1) and matrix Gla protein (MGP) - were examined in kl/kl tibiae. While a widespread osteocalcin staining could be verified in the wild-type bone matrix, localization of the s...

Mineralization in Organic Matrix Frameworks

The primordial earth surface exposed minerals comprised mainly of carbonates, silicates and smaller amounts of phosphates. Weathering eventually led to the dissolution of the surface rock and the leaching of their components into the rivers, lakes and oceans. There, complex chemistry depending upon the temperature, pH, pressure, and atmospheric carbon dioxide content led to the reprecipitation ...
