Because Vitamins A and D are fat soluble, so insufficient fats mean insufficient vitamins A and D
vitamin D deficiency causes lipids
I could be wrong but a vitamin is not a lipid. A lipid is a fat. Vitamin A could be a fat soluble vitamin, but I am not sure if it is. According to my Chem book, Vitamin A is a fat-soluble vitamin and is classified as a lipid. The lab book says to puncture a vitamin A capsule or use cod liver oil, so my guess is it is a triacylglycerol, i.e. an oil.
Vitamin A is lipid soluble.
important cause of ocular morbidity among patients with chronic liver disease and lipid malabsorption, and is a major cause of blindness, corneal keratinization, ulceration, and necrosis. Vitamin A is necessary for normal differentiation of nonsquamous epithelium; keratinization is a direct consequence of its deficiency. What Vitamin "A" is needed for: * Vision * Gene transcription * Immune function * Embryonic development and reproduction * Bone metabolism * Haematopoiesis * Skin health * Reducing risk of heart disease * Antioxidant Activity
For example vitamin E.
For example vitamin E.
what are vitamin hydrosolubles and liposolubles
No. Cholesterol is a lipid and is a precursor to vitamin D and steroid hormones.
Vitamin C is water soluable so the only way it can be transported is by faciliated difficusion using a channel protein. Channel proteins allow polar, watersoluable substances and ions to pass across the cell membrane using faciliated diffusion. Vitamin D is lipid soluble therefore it can pass through using simple diffusion because the phospholipid bilayer lets it pass through down its concentration gradient.
Cholesterol is the lipid used as the precursor for vitamin D synthesis, sex hormones like testosterone and estrogen, and bile acids. It plays a crucial role in the production of these important molecules in the body.
Amino acid based hormones such as Human Growth Hormone is an example of water soluble compounds. Steroid hormones and thyroid hormone are examples of lipid soluble compounds in living humans.
Tay-Sachs is a genetic disease where one of the normally present digestive enzymes is lacking. As a result, a particular lipid in the brain cells cannot be broken down. The resulting build-up of lipids in these cells can cause mental retardation and death.
