Abstract

Glutamic acid is one of constituents of protein or peptide. The free glutamic acid can be absorbed by the stomach and small intestine and also can be utilized by colonic epithelial cells and its microbes. The most of glutamic acid in diets is metabolized in the gastrointestinal tract, which provides plenty of adenosine triphosphate (ATP) to maintain the gut integrity and functions and is used as the main energy source of the gastrointestinal tract. In addition, as the principal precursor of other amino acids and bioactive molecules, glutamic plays nutritional, immunoregulatory and anti-oxidative functions. In the present review, the metabolism of glutamic acid in the gastrointestinal tract and its effects on the health of pigs were summarized.
