Weathering of rocks makes phosphate ions (PO4= and HPO4=) available to plants through uptake from the soil. The mineral apatite contains a small amount of phosphorous, although this is enough for all living things to utilize. Full article >>>
During normal calcification, a major influx of calcium and phosphate ions into the cells accompanies cellular apoptosis and matrix vesicle formation. Full article >>>
The value of fluoride (in ionized form, F−) was first recognized as a preventive for dental caries (cavities). This makes sense because fluoride ions are incorporated along with calcium and phosphate ions in the crystalline structure of which ... Full article >>>
