Collagen material is fibrous, tough, flexible, and highly inelastic. It provides bone with flexibility and resilience. True False The organic portion of the bone is mainly a protein called collagen (type I) and a small amount of noncollagenous material called lipids. Collagen is fibrous, tough, flexible, and highly inelastic; it provides bone with flexibility and resilience . Collagen constitutes 25% to 30% of the weight of dry bone.The remaining weight of dry bone is due to water, at about 5%. Collagen material is fibrous, tough, flexible, and highly inelastic. It provides bone with flexibility and resilience. References

The synthetic crystals of the hydroxyapatite unit cell have two molecules. Therefore, it is usually represented as Ca 10 (PO 4 ) 6 (OH) 2 .True False Bone is the structural material of the human body and is an example of a complex natural composite material. It consists of a mixture of organic and inorganic materials. The inorganic component consists of calcium and phosphate ions and is similar to the synthetic crystals of hydroxyapatite (HA) with the composition Ca 5 (PO 4 ) 3 (OH). Hydroxyapatite is platelike, 20 to 80 nm long and 2 to 5 nm thick, and has a hexagonal crystal system. Since each HA unit cell has two molecules, it is usually represented as Ca 10 (PO 4 ) 6 (OH) 2 . These inorganic minerals, which give bone its solid and hard consistency, constitute 60% to 70% of the dry weight of bone. The synthetic crystals of the hydroxyapatite unit cell have two molecules. Therefore, it is usually represented as Ca 10 (PO 4 ) 6 (OH) 2 .References
