General description

L-Threonine is a naturally occurring amino acid belonging to the aspartate family of amino acids.

Application

L-Threonine has been used for the following :
  • To study the effect of heat on homoserine kinase activity
  • In Plackett–Burman analysis and then to study the effect of selected amino acids on monoclonal antibody production in CHO cells
  • As a substrate to determine the L-threonine dehydrogenase activity
  • To study the effect of L-Threonine on the growth rate of P. putida, to check for its tolerance towards L-Threonine

Packaging

10 mg in glass bottle

Biochem/physiol Actions

L-Threonine is considered to be an essential amino acid. L-Threonine is involved in the synthesis of mucin, a protein supporting intestinal function and integrity. L-Threonine is required for the performance of the immune system. It is also essential for O-linked glycosylation, protein phosphorylation and glycine synthesis.
