L-threonine and the digestive system. A large portion of l-threonine is absorbed in the upper reaches of the small intestine (ileum). Here this amino acid is used to protect the digestive tract. Threonine is needed to produce the mucus gel layer that covers the digestive tract. This mucus is a barrier to digestive enzymes that can damage the intestines. Threonine is also used in other endogenous secretions.
