WebMar 6, 2024 · Threonine (Thr/T) is a polar amino acid that is essential. It is one of three amino acids bearing a hydroxyl group (serine and tyrosine are the others) and, as such, … Threonine (symbol Thr or T) is an amino acid that is used in the biosynthesis of proteins. It contains an α-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 … See more The threonine residue is susceptible to numerous posttranslational modifications. The hydroxyl side-chain can undergo O-linked glycosylation. In addition, threonine residues undergo phosphorylation through the action of a … See more Threonine is one of two proteinogenic amino acids with two stereogenic centers, the other being isoleucine. Threonine can exist in four possible stereoisomers with the following configurations: (2S,3R), (2R,3S), (2S,3S) and (2R,3R). However, the name L-threonine is used … See more Threonine is metabolized in at least three ways: • In many animals it is converted to pyruvate See more • Threonine biosynthesis • CID 205 • CID 6288 See more Threonine was the last of the 20 common proteinogenic amino acids to be discovered.
