Which vitamin class dissolves readily in aqueous solutions?
Show answer Hide answer
Answer: A. C & B complex
Explanation
Water soluble vitamins include all the B complex vitamins and Vitamin C, which dissolve readily in water. Because they dissolve in aqueous environments, the human body does not store excess amounts of them. Any surplus water soluble vitamins are efficiently filtered out by the kidneys and excreted in urine. Vitamins are categorized into water soluble and fat soluble groups based on their chemical solubility. Because they are not stored long term, humans require a continuous daily dietary intake of water soluble vitamins. Cooking methods like boiling vegetables in water can leach out these delicate vitamins if water is discarded.
D and K complex vitamins belong to the fat soluble category and dissolve in lipids instead of water. A and D complex vitamins require dietary fats for proper absorption and storage in body tissues. B1 and B2 are water soluble, but grouping them exclusively excludes Vitamin C and other B vitamins.
