Phosphate Ion (Intestinal) (PO43- (Intestinal))

The phosphate ion (PO43-) is a crucial inorganic anion absorbed in the intestine and involved in numerous biological processes, including energy metabolism, bone mineralization, signal transduction, and pH buffering. Intestinal phosphate absorption occurs via both paracellular (passive) and transcellular (active) pathways, regulated by factors such as dietary intake, hormones (Vitamin D), and transporters (Npt2b). Therapeutic strategies targeting intestinal phosphate absorption are primarily used to manage hyperphosphatemia, especially in chronic kidney disease.
