5-HTP is the precursor to serotonin. It improves mood, anxiety and is beneficial in weight loss. 5-Hydroxytryptophan (5-HTP) is an amino acid that is the intermediate step between tryptophan and the important brain chemical serotonin. There is a massive amount of evidence that suggests that low serotonin levels are a common consequence of modern living.
Amino information
Chemistry will tell you that an amino acid is any molecule that has both carboxylic acid and amino functional groups. They are the basic building units of a protein. In biochemistry, the shorter and more general term is used to refer to alpha amino acids. Those are amino acids wherein the amino and carboxylate functionalities are attached to a common carbon. Amino acids’ residue is what’s left of an amino acid once a water molecule has been lost in the formation of a peptide bond.
