What molecule does the large intestine mainly reabsorb?

Explanation:
Water is the molecule mainly reabsorbed by the large intestine. The colon absorbs electrolytes like Na+ and Cl− and, as these ions are taken up, water follows by osmosis, turning the contents into solid feces. While some vitamins and a small amount of short-chain fatty acids can be absorbed there, nutrients like glucose and proteins are primarily reabsorbed earlier in the small intestine, and bile salts are mainly reabsorbed in the ileum.
