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.
Why does vitamin A status depend on a persons protein status?
Transport of the vitamin within the body requires sufficient protein to manufacture retinol-binding protein.
Does protein promote calcium absorption?
No, protein helps give you energy. Vitamin D helps absorb calcium
How does smoking affect the absorption of vitamin C in the body?
Smoking can decrease the absorption of vitamin C in the body. This is because smoking can damage the cells in the digestive system that are responsible for absorbing nutrients, including vitamin C. As a result, smokers may have lower levels of vitamin C in their bodies compared to non-smokers.
What transports vitamin a?
"After absorption via the lymph system, vitamin A eventually arrives at the liver, where it is stored. There, a special transport protein, retinol-binding protein (RBP), picks up vitamin A from the liver and carries it in the blood."(Understanding Nutrition, volume 12, chapter 11 page 356)
What vitamin absorption increases in older adults?
vitamin A
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 gland increases blood calcium level stimulates calcium re-absorption and activates vitamin D?
The parathyroid gland is responsible for increasing blood calcium levels by stimulating calcium re-absorption in the kidneys and activating vitamin D, which helps in calcium absorption in the intestines.
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.
Which vitamin provides for the absorption of calcium and phosphorus by bones and teeth?
Vitamin D is responsible for aiding in the absorption of calcium and phosphorus by bones and teeth. It helps regulate the levels of these minerals in the body to maintain strong and healthy bones and teeth. Sunlight exposure is a natural way for the body to produce vitamin D.
Which vitamin enhances the absorption of insulin?
Animal studies have concluded that vitamin C enhances chromium absorption of insulin.
Which organ absorbs water and vitamin k from digested food?
The colon (large intestine) is responsible for absorbing water and vitamin K from digested food. Water absorption helps to form solid waste, while vitamin K absorption is important for blood clotting and bone health.
