Your body gets vitamin A from food sources such as liver, carrots, butter, egg, milk, and many more. In these foods there are the many forms of vitamin A. Some forms include Retinol, alpha-carotene, beta-carotene, as well as 2 or 3 more carotenes. Your body does not make vitamin A; it absorbs it.

No - Vitamin D is not a sugar. The various forms of Vitamin Ds are involved in the regulation of the calcium and phosphorous levels within the body.
Vitamin A is a fat-soluble vitamin that exists in different forms, including retinol, retinal, retinoic acid, and provitamin A carotenoids. Retinol is the form of vitamin A that is most easily absorbed by the body and is found in animal-based foods such as liver, egg yolks, and dairy products.
The body stores excessive Vitamin A in the liver for later use if needed. Vitamin D however needs to be converted to a different form to be biologically active. This conversion after it leaves the liver, occurs in the kidney where it is converted to 1,25-dihydroxycholecalciferol, a biologically active form.

Vitamin K is converted to active vitamin K in the body which helps to activate clotting factors in the liver. Coumadin (warfarin) prevents the body from activating vitamin K, therefore the clotting factors are never activated and your blood becomes thinner or more difficult to clot. When you eat vitamin K rich foods (green leafy vegitables, etc), the vitamin K competes with the Coumadin and can neutralize its effect.
No. All the B vitamins are different and serve different purposes in the body.
Folate is vitamin B9 ((pteroylmonoglutamate). It is not iron but works with the body using iron in your blood.
