L-Tryptophan-Feed Grade
CAS NO.: 54-12-6
Molecular Formula: C5H11NO2S Molecular Weight: 149.21
Structural Formula:
Properties:
L-Tryptophan is one of the 20 standard amino acids, as well as an essential amino acid in the human diet. It is encoded in the standard genetic code as the codon UGG. Only the L-Stereoisomer of L-Tryptophan is used in structural or enzyme proteins, but the D-Stereoisomer is occasionally found in naturally produced peptides (for example, the marine venom peptide contryphan). The distinguishing structural characteristic of Tryptophan is that it contains an indole functional group.

Used:
L-Tryptophan is one of essential amino acids and the fourth limiting amino acid in animal diets, which means L-Tryptophan could not be synthesized by the body, in addition, dietary supply through feed materials is usually insufficient. The deficiency of L-Tryptophan was generally characterized as decreased feed intake and efficiency, and slow growth rate. Considering L-Tryptophan playing a key role in growth performance and feed efficiency, L-Tryptophan is recommended to add L-Tryptophan in diet to achieve the optimal amino acid balance and fulfill the digestible L-Tryptophan requirement of animals, especially piglets, sows and poultry etc.
Packing and Storage:
L-Tryptophan is packed in 25kg/drum. L-Tryptophan should be stored in cool and air place.
Shelf life:
2 years in original packages
