What else can I help you with?
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.
What vitamins help the body to use protein?
Vitamins B6, B12, and C play important roles in helping the body utilize protein. Vitamin B6 helps in the metabolism of amino acids, vitamin B12 aids in the synthesis of proteins, and vitamin C helps in the absorption of iron which is needed for protein production.
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.
Who is most likely to be vitamin B12 deficient?
Individuals following a vegan or vegetarian diet, older adults, and those with certain gastrointestinal conditions (such as pernicious anemia or celiac disease) are most likely to be vitamin B12 deficient. Additionally, individuals who have had weight loss surgery or take certain medications that interfere with vitamin B12 absorption may also be at risk.
What is the major role of absorption in the illeum?
The function of the ileum is mainly to absorb vitamin B12 and bile salts and whatever products of digestion were not absorbed by the jejunum.
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.
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.
How long does it take for vitamin b12 to be absorbed?
It takes approximately 24 hours for the absorption of vitamin B12. For quicker absorption, you can get a B12 shot.
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.
Where the parietal cells of the stomach is necessary for vitamin B12 absorption?
Parietal cells in the stomach are essential for vitamin B12 absorption because they produce intrinsic factor, a glycoprotein crucial for the absorption of vitamin B12 in the small intestine. When food enters the stomach, vitamin B12 binds to intrinsic factor, forming a complex that protects it from digestion. This complex is then absorbed in the ileum, the final part of the small intestine. Without intrinsic factor, vitamin B12 cannot be effectively absorbed, leading to potential deficiencies.
What vitamins help the body to use protein?
Vitamins B6, B12, and C play important roles in helping the body utilize protein. Vitamin B6 helps in the metabolism of amino acids, vitamin B12 aids in the synthesis of proteins, and vitamin C helps in the absorption of iron which is needed for protein production.
What carrier protein is responsible for absorption of vitamin B12?
Intrinsic factor
What substance is necessary for the absorption of vitamin b?
Intrinsic factor is the substance necessary for the absorption of vitamin B12. It is a glycoprotein produced by the stomach's parietal cells and is essential for the binding and absorption of vitamin B12 in the small intestine. Without intrinsic factor, the body cannot effectively absorb vitamin B12, leading to deficiencies. This is particularly important for preventing conditions like pernicious anemia.
What vitamin does Intrinsic factor facilitates its absorption from the small intestine?
Intrinsic factor facilitates the absorption of vitamin B12 from the small intestine. This glycoprotein, produced by the stomach's parietal cells, binds to vitamin B12, allowing it to be absorbed in the ileum. Without intrinsic factor, the body cannot effectively absorb vitamin B12, leading to deficiencies and associated health issues.
What vitamin aids in the absorption of calcium and phosphorus?
Vitamin D aids in absoprtion of calcium and Phosphorus. Along with other beneficial effects.
What enables absorption of b12 across small intestine wall?
Intrinsic factor, a protein produced by the stomach, is required for the absorption of vitamin B12 in the small intestine. In the small intestine, vitamin B12 binds to intrinsic factor, forming a complex that can be absorbed through the intestinal wall.
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.
