This is in distinct contrast to most foods containing the three major energy sources: carbohydrates, proteins, and fats. Most of these are large, complex molecules that must be broken down into smaller molecular fragments by stomach acid or digestive enzymes in the mouth or small intestine to be absorbed. Absorption of alcohol begins immediately after the first swallow and continues until the last fragment is absorbed in the small intestine.
