Which nutrient requires intrinsic factor for absorption?
Vitamin B12 requires intrinsic factor for absorption in the small intestine. Intrinsic factor is produced by the stomach and binds to vitamin B12 to facilitate its absorption in the ileum. Without intrinsic factor, vitamin B12 absorption is impaired, leading to deficiency.
What vitamin requires intrinsic factor in order to be bsorbed?
vitamine b12
Which vitamin need instritic factor for stomach for absortion?
B12 is the vitamin that requires intrinsic factor for absorption. B12 is also known as cobalamin.
Aids in absorption of vitamin b12?
Intrinsic factor, a protein produced in the stomach, helps in the absorption of vitamin B12. This vitamin is crucial for red blood cell formation and neurological function. Absorption of vitamin B12 occurs in the small intestine, where it binds to intrinsic factor for transport into the bloodstream.
What the importance of intrinsic factor?
Intrinsic factor is glycoprotein that is produced by the parietal cells of the stomach.
How pernicious anemia cause achlorhydria?
pernicious anemia is a vitamin B12 deficiency. Vitamin B12 requires Intrinsic Factor to be reabsorbed by the ileum. Intrinsic Factor is produced by parietal cells in stomach. If there is some damage or manipulation of parietal cells, which also produce HCl, there will be less of both intrinsic factor causing B12 deficiency and HCl causing achlorhydria.
Where does the absorption of vitamin B12 occur?
The vitamin B12 is a very important nutrient; it lowers risk of stroke, heart disease, cancer, Parkinson's, and Alzheimer's disease. The vitamin begins to absorb in the mouth, in contrast to most nutrients.
A protein secreted by the stomach that is necessary for the absorption of vitamin B12?
The protein secreted by the stomach that is necessary for the absorption of vitamin B12 is called intrinsic factor. Intrinsic factor binds to vitamin B12 in the small intestine, allowing for its absorption into the bloodstream. Without intrinsic factor, vitamin B12 cannot be effectively absorbed and can lead to a deficiency.
Why do you need intrinsic factor?
Intrinsic factor or gastric intrinsic factor is a protein produced by the stomach. It is used to absorb vitamin B12 in the small intestine. When there is a deficiency of the Intrinsic factor, there is a deficiency in the absorption of B12 into the body and this leads to pernicious anemia.
What role does the intrinsic factor play in the absorption of which nutrient?
The intrinsic factor plays a crucial role in the absorption of vitamin B12 in the small intestine.
Which cells produce intrinsic factor?
Intrinsic factor is produced in the fundus and body of the stomach by parietal cells that line the stomach. The purpose of intrinsic factor is so vitamin B can be absorbed in the small intestine.
Why oral administration of vitamin B12 not effective as a treatment of pernicious anemia?
Pernicious anemia is due to a deficiency of a vitamin called intrinsic factor, which is normally produced by cells of the stomach. Intrinsic factor is required for the absorption of vitamin B12, so if intrinsic factor levels are insufficient, vitamin B12 will not be absorbed well. So administration of vitamin B12 will only help treat vitamin B12-deficiency anemia if vitamin B12 can be absorbed, and this can only happen if there are adequate levels of intrinsic factor to begin with. Patients with pernicious anemia do not have adequate intrinsic factor levels, so they will not be helped by vitamin B12 treatment since they can't absorb it well enough.
