Does absorption of nutrients occur in the stomach?

Absorption of nutrients does not occur in the stomach. Most carbohydrates, lipids, and proteins are only partially broken down by the time they leave the stomach and cannot be absorbed. In addition, the lining of the stomach is covered with alkaline cells so the acidic chyme is not in direct contact with the stomach lining. It is relatively impermeable to water. Absorption of nutrients occurs after the chyme has left the stomach.
