Phosphate absorption
WebVitamin D functions by stimulating intestinal calcium and phosphorus absorption, by stimulating bone calcium mobilization, and by increasing renal reabsorption of calcium in the distal tubule. These functions on bone and possibly kidney, but not intestine, require the parathyroid hormone. WebSep 4, 2024 · Phosphorus absorption mainly takes place in the duodenum and jejunum; most phosphorus is absorbed in its inorganic state. Organic phosphorus is hydrolyzed enzymatically by phospholipase and alkaline phosphatase and released as inorganic phosphate. Up to 70% of phosphorus is absorbed in the gut, and occurs through two …
