The chemistry of aluminum as related to biology and medicine.
TL;DR: Al3+ is expected to complex with oxygen donor ligands, especially phosphates, and it does so in soils, in the gastrointestinal tract, and in cells, and an appreciable fraction occurs as a neutral complex that may pass through membranes and provide a vehicle for Al3+ absorption into the body.
