Threonine (symbol Thr or T)[2] is an amino acid that is used in the biosynthesis of proteins. It contains an -amino group (which is in the protonated NH+ 3 form under biological conditions), a carboxyl group (which is in the deprotonated COO form under biological conditions), and a side chain containing a hydroxyl group, making it a polar, uncharged amino acid. It is essential in humans, meaning the body cannot synthesize it: it must be obtained from the diet. Threonine is synthesized from aspartate in bacteria such as E. coli.[3] It is encoded by all the codons starting AC (ACT, ACC, ACA, and ACG) For price, specification and other details please contact us.
