L-threonine is an essential amino acid, which means the human body cannot produce it and we need to obtain it from our diet. It plays an important role in protein production and metabolism of carbohydrates and fats. Threonine also contributes to the production of enzymes, which are necessary for various chemical reactions in the body.
