L-TRYPTOPHAN Overview Information. L-tryptophan is an amino acid, a protein building block that can be found in many plant and animal proteins. L-tryptophan is called an âessentialâ amino acid because the body canât make it. It must be acquired from food.
IN addition to being a substrate for protein synthesis in the body, dietary tryptophan is metabolized to at least two physiologically important compounds, nicotinic acid and serotonin, via the intermediates outlined in Figure 1Figure 1 Main Metabolic Pathways of Tryptophan.
