Nutrient Absorption in the Stomach: Alcohol, Protein, and Fat

All above

The stomach is a J-shaped organ that is located in the upper left portion of the abdomen. It is responsible for the initial stages of digestion, which includes the breakdown of food and the absorption of nutrients.

Alcohol, protein, and fat are all absorbed in significant quantities by the stomach. Alcohol is absorbed directly into the bloodstream through the walls of the stomach. Protein is broken down into amino acids, which are then absorbed into the bloodstream. Fat is broken down into fatty acids and glycerol, which are then absorbed into the lymphatic system.
