The acidic macromolecules in rabbit cortical bone tissue
Abstract:
Rabbit cortical bone powder was extracted with EDTA solutions at neutral pH and the soluble constituents fractionated by DEAE-cellulose chromatography. The acidic fractions obtained were further investigated by gel chromatography and chemical analysis. Two classes of proteoglycans were present; one containing chondroitin sulphate and the other containing material resembling keratan sulphate mixed with a smaller amount of chondroitin sulphate. Sialoglycoproteins were detected by specific chemical introduction of tritium label into the sialic acid residues of the acidic glycoprotein fraction. Following sodium dodecyl sulphate-polyacrylamide gel electrophoresis and fluorography, the presence of numerous distinct sialoglycoprotein components was demonstrated.

Bone as Supporting Connective Tissue
Bone Matrix
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts— mostly calcium salts— that give the...

Osteoblasts and Osteocytes
The osteoblast is the bone cell responsible for forming new bone tissue. It is found in the growing portions of bone, including the periosteum and...

Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
