L-Tryptophan

Introduction

Product properties: L-Tryptophan has the bitter taste, the DL- and the D- type have little sweet taste. 289 °C decompounds,

slightly soluble in water, does not dissolve in the ethyl alcohol. It’s appearance is white-like crystalline powder. Tryptophan is an

α-amino acid that is used in the biosynthesis of proteins. Tryptophan contains an α-amino group, an α-carboxylic acid group, and

a side chain indole, making it a non-polar aromatic amino acid. It is essential in humans, meaning the body cannot synthesize it，

it must be obtained from the diet.

Functions: Amino acids, including tryptophan, are used as building blocks in protein biosynthesis, and proteins are required to

sustain life. Many animals (including humans) cannot synthesize tryptophan: they need to obtain it through their diet, making it

an essential amino acid. Tryptophan is among the less common amino acids found in proteins, but it plays important structural or

functional roles whenever it occurs. For instance, tryptophan and tyrosine residues play special roles in "anchoring" membrane

proteins within the cell membrane.
