Is galactose an aldehyde
WebMar 27, 2024 · 3,6-anhydro-α-L-galactose (L-AHG) is one of the main monosaccharide constituents of red macroalgae. In the recently discovered bacterial L-AHG catabolic pathway, L-AHG is first oxidized by a NAD(P)+-dependent dehydrogenase (AHGD), which is a key step of this pathway. However, the catalytic mechanism(s) of AHGDs is still unclear. WebApr 6, 2024 · Answer: Sugars with a free aldehyde or ketone group in their structure can reduce or donate an electron during a chemical reaction, making them reducing sugars. While all monosaccharides are reducing sugars, this group also includes certain disaccharides and polysaccharides. Since it contains a free aldehyde group, galactose is …

WebTools. An aldose is a monosaccharide (a simple sugar) with a carbon backbone chain with a carbonyl group on the endmost carbon atom, making it an aldehyde, and hydroxyl groups connected to all the other carbon atoms. Aldoses can be distinguished from ketoses, which have the carbonyl group away from the end of the molecule, and are therefore ... WebGalactose is a monosaccharide and has the same chemical formula as glucose, i.e., C6 H 12 O 6. It is similar to glucose in its structure, differing only in the position of one hydroxyl group. This difference, however, gives galactose different chemical and biochemical properties to glucose.
