The absorption of water by the large intestine not only helps to condense and solidify feces, but also allows the body to retain water to be used in other metabolic processes. Ions and nutrients released by gut bacteria and dissolved in water are also absorbed in the large intestine and used by the body for metabolism.

Are amino acids absorbed from the large intestine?

This score depends on ileal amino acid (AA) digestibility; therefore, the assumption is made that AAs are not absorbed in nutritionally relevant amounts from the large intestine.

How is absorption regulated in the gastrointestinal tract?

Regulation of Absorption. Absorption in the gastrointestinal tract is regulated by neuroendocrine mechanisms. In the colon endocrine mechanisms used include: Aldosterone – increases the net absorption of water and electrolytes by stimulating the basolateral sodium-potassium ATP-ase.
