As calcium is required for bone development, many bone diseases can be traced to the organic matrix or the hydroxyapatite in molecular structure or organization of bone. Osteoporosis is a reduction in mineral content of bone per unit volume, and can be treated by supplementation of calcium, vitamin D, and bisphosphonates .
Calcium makes up 920 to 1200 grams of adult body weight, with 99% of it contained in bones and teeth. This is about 1.5% of body weight. [ 2 ] Phosphorus occurs in amounts of about 2/3 of calcium, and makes up about 1% of a person's body weight. [ 10 ]
Vivianite is a secondary mineral found in a number of geologic environments: the oxidation zone of metal ore deposits, in granite pegmatites containing phosphate minerals, in clays and glauconitic sediments, and in recent alluvial deposits replacing organic material such as peat, lignite, bog iron ores and forest soils (all).
Eating prunes every day may help keep your bones strong as you age, a new study finds. Researchers say that 4-6 daily could maintain bone density and strength. ... Prunes are rich in vitamin K ...
Bone Mineral Density (BMD) tends to peak at a young age. When children are younger, they start building up their BMD through their nutrition and through exercise. BMD peaks at around 12.5 years old for girls and around 14 years old for boys. [23] It could be caused by a deficiency in calcium or Vitamin D. Calcium is the main nutrient for bone ...
Dietary calcium and phosphorus ratio, along with vitamin D, regulates bone mineralization and turnover by affecting calcium and phosphorus transport and absorption in the intestine. [ 4 ] It has been suggested that osteophagy is an innate behavior that allows animals to supplement their phosphorus and calcium uptake in order to avoid the costly ...
The most common biogenic phosphate is hydroxyapatite (HA), a calcium phosphate (Ca 10 (PO 4) 6 (OH) 2) and a naturally occurring form of apatite. It is a primary constituent of bone, teeth, and fish scales. [33] Bone is made primarily of HA crystals interspersed in a collagen matrix—65 to 70% of the mass of bone
Bones may weaken to such a degree that a break may occur with minor stress or spontaneously. After the broken bone heals, some people may have chronic pain and a decreased ability to carry out normal activities. [3] Osteoporosis may be due to lower-than-normal maximum bone mass and greater-than-normal bone loss.
