31 maj 2021 · In this article, we focus on mammalian calcium absorption across the intestinal epithelium in normal physiology. Intestinal calcium transport is essential for supplying calcium for metabolism and bone mineralization.
1 lut 2009 · Calcium absorption proceeds by transcellular and paracellular flux, with the latter accounting for most absorbed calcium when calcium intake is adequate. Vitamin D helps regulate transcellular calcium transport by increasing calcium uptake via a luminal calcium channel and by inducing the cytosolic calcium transporting protein, calbindinD 9k ...
Calcium absorption by the large bowel can assume nutritional importance under conditions of significant small bowel resection. Key Words: calbindin D 9k. active calcium transport. passive calcium transport. small intestine. large intestine. effects of varying calcium intake.
1 mar 2016 · Here, we reviewed the key mechanisms of calcium homeostasis, including calcium sensing receptor regulation, intestinal calcium absorption, renal calcium reabsorption and bone calcium resorption. We further discussed the roles of dietary calcium and vitamin D in diseases associated with dysfunctional regulation of calcium.
If normal serum calcium is unable to be maintained by intestinal absorption, then 1,25(OH) 2 D 3 together with PTH will mobilize bone calcium and increase reabsorption of calcium from the renal distal tubule.
Objective: We reexamined this mechanism by evaluating the effect of 2 amounts of dietary protein (low: 0.7 g/kg; and high: 2.1 g/kg) on fractional calcium absorption in 7 healthy, young women.
28 cze 2020 · The intestinal Ca2+ absorption occurs mainly via the paracellular and the transcellular pathways. The proteins involved in both ways are regulated by calcitriol and other hormones as well as...
