Lgalactarate

Lgalactarate is the anionic form of L-galactaric acid, also known as mucic acid. It is a dicarboxylic acid that is derived from galactose. L-galactarate is a relatively rare sugar acid and is not a common component of biological systems. It can be found in small amounts in some plants and microorganisms.

Chemically, L-galactarate has the molecular formula C6H10O8. It is a white crystalline solid that is soluble in water. Its structure consists of a six-carbon chain with carboxyl groups at both ends and hydroxyl groups on the remaining four carbons, with a specific stereochemistry defining it as the L-isomer.

The metabolism of L-galactarate is not well understood. In some bacteria, it can be degraded through a pathway that involves several enzymatic steps, ultimately leading to intermediates that can enter central metabolic pathways. However, in most organisms, it is not readily metabolized and can accumulate.

L-galactarate has found some limited applications. It has been explored as a potential ingredient in certain industrial processes and as a precursor for the synthesis of other chemical compounds. Its physical properties, such as its acidity and chelating abilities, have also been of interest. Research into its biological roles and potential applications is ongoing.
