L-Erythrulose is an organic compound that is a sugar alcohol. It can be synthesized from the aldol reaction of glycolaldehyde and dehydroascorbic acid, which are both found in natural sources. L-Erythrulose has shown to have intramolecular hydrogen transfer (H-transfer) reactions, where the hydroxyl group migrates from one C atom to another. This kinetic data was obtained using surface methodology on model systems containing l-erythrulose and bacteria with wild-type or mutant strains. The conformational properties of L-erythrulose were also investigated by comparing its chemical structures with those of other sugars.

The modification of a polysaccharide with an oligosaccharide, which is the process of adding one or more sugar residues to the polysaccharide. This can be done enzymatically or chemically. The addition of a carbohydrate residue to another carbohydrate-bearing molecule. This can be done enzymatically or chemically. The synthesis of an organic compound that contains only carbon, hydrogen, and oxygen atoms in its molecular structure. This can be done enzymatically or chemically. The process of adding a methyl group to an organic compound. This can be done enzymatically or chemically. A monosaccharide is a simple sugar that cannot be hydrolyzed into simpler sugars by chemical means. It is one of the three main types of biomolecules found in living things (along with lipids and nucleic acids). Methylation is a chemical reaction involving the transfer of a methyl group from one chemical entity to another one; for example, from methanol to dim
