What properties do water-soluble vitamins share?
Water-soluble vitamins are dissolvable in water. They are digested, absorbed, and transported in similar ways. Most absorption takes place in the small intestine, although some may occur in the stomach. Many water-soluble vitamins are bound to proteins that must be removed before absorption. They travel through the blood to the liver. They are not actively stored, so generally they do not cause toxicity when consumed in large amounts. They are easily destroyed by common cooking and storage techniques.
