Abstract:
The collagen network in bone provides resistance against fracture and may be susceptible to changes with aging and disease. This review identifies the changes in quality of collagen matrix as contributors to bone fragility. With aging and in diabetes, cross-links accumulate in bone collagen as a result of nonenzymatic glycation and consequently impair matrix properties, increasing bone fragility. Cell-culture and animal studies suggest that the accumulation of cross-links induced by nonenzymatic glycation may be related to a reduction in bone turnover resulting from the altered responses of osteoblasts and osteoclasts to advanced glycation end products.

The Bone Matrix
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
