Summary
Threonine, which abbreviates to the 3-letters Thr or one-letter T, is one of the 20 amino acids that make up proteins in our body. Threonine’s R-group is a 2 carbon chain with a hydroxyl attached to the first carbon. Because of its hydroxyl group, threonine can be phosphorylated. Threonine is also a polar, hydrophilic amino acid, with a neutral charge at physiological pH.
