Description
L-Threonine (CAS 72-19-5) is an essential amino acid used mainly in animal feed, and also in food, pharmaceutical and cell culture applications. Zyntex is a wholesale supplier and distributor of feed- and pharma-grade L-Threonine, with a CoA and SDS for every lot.

L-Threonine Product Overview

L-Threonine (C4H9NO3) is a white crystalline powder that dissolves in water. Animals and humans cannot make it themselves, so it must come from the diet. Commercial L-threonine is produced by bacterial fermentation and then crystallized.

In pig and poultry diets, threonine is typically one of the first limiting amino acids after lysine and methionine. Feed producers therefore add it to compound feed so they can lower crude protein levels while keeping performance, which also reduces nitrogen excretion. It often appears in premixes with DL-Methionine and L-Tryptophan.

Pharmaceutical and biotech companies use high-purity grades in infusion solutions and cell culture media. Food producers use it in fortified foods. For other amino acids, see L-Serine and L-Tyrosine.
