PURE Tryptophan Capsules – An essential amino acid
Tryptophan is an essential amino acid and serves as a precursor for various substances produced by the body. PURE Tryptophan Capsules from Edubily give you 250 mg of pure L-tryptophan per capsule – with no additives or fillers.
Tryptophan as a biochemical precursor
Tryptophan is one of the rarer amino acids found in proteins – yet it often plays a crucial structural or functional role there. Tryptophan and tyrosine residues, for example, help anchor membrane proteins stably in the cell membrane. Together with other aromatic amino acids, tryptophan is also involved in specific interactions between proteins and glycans – an aspect that is of particular interest in the field of cell communication and immune response.
