6Deoxygalactose

6-Deoxygalactose, also known as L-galactose or galactan, is a deoxysugar and a derivative of galactose. In this molecule, the hydroxyl group at the sixth carbon atom of galactose is replaced by a hydrogen atom. It is a naturally occurring monosaccharide found in some plants and microorganisms. 6-Deoxygalactose is an epimer of 6-deoxyglucose (rhamnose). It can exist in both cyclic and open-chain forms. The cyclic forms are typically furanose or pyranose rings. Its chemical formula is C6H12O5. While not as common as its parent sugar, galactose, 6-deoxygalactose plays a role in the biosynthesis of certain polysaccharides and may be involved in microbial metabolism. It can be found as a component of some bacterial cell wall polysaccharides and is sometimes used in research settings to study carbohydrate metabolism and enzyme activity. Its structural similarity to other hexoses allows it to interact with certain carbohydrate-binding proteins and enzymes.
