Structurally,how are water-soluble and fat-soluble vitamins different?

Question

Quizplus · Accepted Answer

Water-soluble vitamins contain polar functional groups, such as OH, which make them easily dissolve in water, while fat-soluble vitamins do not contain such groups and require fat for absorption. The number of atoms and molecular masses of vitamins do not determine their solubility in water or fat. The statement about storage in urine is incorrect, as excess water-soluble vitamins are typically excreted in urine, while excess fat-soluble vitamins can accumulate in body fat and cause toxicity.
