threonate

Threonate refers to the salt or ester of threonic acid. Threonic acid is a sugar acid derived from the oxidation of the aldehyde group of threose, a four-carbon aldose sugar. Threonic acid exists as two stereoisomers: D-threonate and L-threonate, corresponding to the D and L forms of threose.

In biological contexts, threonate is most notably associated with magnesium L-threonate, a compound formed by the combination of L-threonic acid and magnesium. This specific form has gained attention for its purported ability to cross the blood-brain barrier more effectively than other magnesium salts. Research has explored its potential role in cognitive function and brain health, with some studies suggesting it may support memory and learning.

Threonic acid itself can be produced through the oxidation of threose. While not as common as other sugar acids like gluconate, it is a naturally occurring compound and can be found in certain foods. The biological significance and therapeutic applications of threonate, particularly in the form of magnesium L-threonate, are areas of ongoing scientific investigation.
