What exactly is the difference between water-soluble and fat-soluble vitamins?

Vitamins: Fat soluble (a, d, e, k) have to be processed for absorption with enzymes that digest fat. They can be stored in fatty storage areas so if too much taken, toxicity can occur. Vitamin d from sun is controlled by body's storage and processing to avoid that. Water soluble vitamins typically not stored so need to be taken daily.
