L-Threonine Structure

Synonyms: L-Threonine, (2S,3R)-2-Amino-3-hydroxybutanoic acid, L-α-Amino-β-hydroxybutyric acid, Threonine

L-Threonine is a proteinogenic amino acid with the chemical formula C4H9NO3 and a molecular weight of 119.12 g/mol. As an essential amino acid, it cannot be synthesized by the human body and must be obtained through diet or supplementation. It is one of the three major limiting amino acids in cereal proteins, alongside lysine and methionine.

In the pharmaceutical and nutraceutical industries, L-Threonine is valued for its role in protein synthesis, immune function, and gastrointestinal health. It is also a key component in total parenteral nutrition (TPN) solutions and is used as a precursor in the production of antibiotics and other bioactive compounds. Its versatility extends to animal feed, where it improves growth performance and reduces nitrogen excretion.
