DL-Threonine by MP Biomedicals is a high purity amino acid. Threonine is an amino acid which is used in the biosynthesis of proteins. This preparation is available as a white powder which is soluble in water. It contains an -amino group, a carboxyl group, and a side chain containing a hydroxyl group, which makes it a polar, uncharged amino acid. In humans, the body cannot synthesize it as it is essential, and hence must be obtained from outside. In bacteria such as E. coli, threonine is synthesized from aspartate. It is majorly found in cottage cheese, poultry, fish, meat, lentils, Black turtle bean and Sesame seeds. CAS No. 80-68-2 Quantity Provided: 500 mg per pack Molecular Formula: C4H9NO3 Molecular Weight: 119.1 Soluble in water DL-Threonine is widely used in chemical and biological sectors. DL-Threonine is used as an additive to animal feed. They are also used to chelate metal cations in order to improve the absorption of minerals from supplements, which may be required to improve the health or production of animals. This chelating ability is also used in fertilizers for agriculture. Racemic threonine can be prepared from crotonic acid by alpha-functionalization using mercury(II) acetate.
