Vitamin E
Erythrocyte Hemolysis
This rupturing of red blood cells leads to anemia, a condition in which the red blood cells cannot carry and transport enough oxygen to the tissues, leading to fatigue, weakness, and a diminished ability to perform physical and mental work
spreads, salad dressings, and mayonnaise made from vegetable oils, including safflower oil, sunflower oil, canola oil, and soybean oil. Nuts, seeds, soybeans, and some vegetables—including spinach, broccoli, and avocados— also contribute vitamin E to our diets
What are the food sources for Vitamin E?
results of diseases that cause malabsorption of fat, such as those that affect the small intestine, liver, gallbladder, and pancreas.
What can being deficient in Vitamin E cause?
hemorrhaging in the brain, leading to hemorrhagic stroke
What can long term use of Vitamin E supplements may cause?
it opposes excessive clot formation of blood that is promoted by free radical -important for early and fetal development of nerves and muscles -helps protect white blood cells and improves the absorption of Vitamin A
What does are the anticoagulant properties for Vitamin E?
Erythrocyte Hemolysis
What is the Vitamin E deficiency symptom?
nausea, intestinal distress, and diarrhea
what are recorded side effects from Vitamin E supplementation?
Tocotrienols and tocopherols
what are the two separate families of compounds for Vitamin E?
- protects LDLs from being oxidized, lowering the risk of cardiovascular disease -protects against the membranes of red blood cells from oxidation and plays a critical role in protecting the cells of our lungs
what are two functions of Vitamin E?
VLDL and LDL
what is Vitamin E both a part of in their transportation to the tissues and cells of both lipoproteins?
anticoagulants -substances that stop blood from excessively clothing Ex: Aspirin
what is a medicine that interacts negatively with Vitamin E and what is its function?
-It is absorbed with dietary fat and incorporated into the chylomicrons. -As the chylomicrons are broken down, most of the vitamin E remains in their remnants and is transported to the liver. -There, vitamin E is incorporated into very- low-density lipoproteins (VLDLs) and released into the blood. -After VLDLs release their triglyceride load, they become LDLs.
what is the absorption of Vitamin E?
Because vitamin E is prevalent in adipose tissue and cell membranes, its action specifically protects polyunsaturated fatty acids (PUFAs) and other fatty componentsof our cells and cell membranes from being oxidized
what is the action of Vitamin E with PUFAs?
90% adipose tissue and remaining is in cell structure
what is the best storage site of Vitamin E?
alpha tocopherol
what is the most active form of Vitamin E found in food and supplements in the body?
Acts as an antioxidant by donating an electron to free radicals, stabilizing them, and preventing them from destabilizing other molecules. -Once Vitamin E is oxidized, it is either excreted or recycled back into the body
what is the primary role of Vitamin E?
fat-soluble key antioxidant
what type of vitamin is Vitamin E?
tocopherols
-a family of Vitamin E that is the active form in our bodies -active forms of alpha, beta, gamma, and delta
tocotrienols
-a family of vitamin E that does not play an important biological role in our bodies -consist of alpha, beta, gamma, and delta (not active in the body)
alpha-tocopherol equivalent in milligrams
on food labels, vitamin and mineral supplement, often use express vitamin E in which unit?
loss of muscle coordination and reflexes, leading to impairments in vision, speech, and movement, and can reduce immune function, especially when body stores of the mineral selenium are low.
