L-Psicose is a monosaccharide that is the only metabolite of D-fructose. It is found in many living organisms, such as bacteria and fungi. L-Psicose has been shown to inhibit ribitol dehydrogenase, an enzyme involved in the production of ribitol, which catalyzes the conversion of ribitol to ribulose 5-phosphate. Ribulose 5-phosphate is an important precursor molecule for glycolysis and pentose phosphate pathways. In addition, L-psicose has been shown to bind to proteins through hydrogen bonding, which may prevent the protein from folding properly or interacting with other molecules. This binding can lead to cell death if it inhibits essential cellular functions.

B-D-glucose is a monosaccharide with the molecular formula C6H12O6. It is the major form of glucose in plants, and is one of the simplest carbohydrates.

The hydroxyl group of b-D-glucose reacts with p-hydroxybenzoic acid to form a new compound called glucopyranosiduronic acid. The hydroxyl group also reacts with sodium citrate to form sodium hydrogen citrate. This reaction can be used to measure the concentration of b-D-glucose in an unknown solution using high performance liquid chromatography (HPLC). B-D-glucose has been shown to have antidiabetic activity, as it improves insulin sensitivity, reduces blood glucose levels, and decrease body mass index (BMI) in animal models. A model system

2-Deoxy-scyllo-inosose is a biochemical with an unknown function. It is not a substrate for any known enzyme, but has been shown to be a substrate for the synthesis of corynebacterium glutamicum. The reaction mechanism of 2-deoxy-scyllo-inosose is still unclear, but it has been proposed that this molecule undergoes dehydration and then undergoes an acid catalyzed aldol cyclization to form 3-aminohexanol. This reaction produces fluorescence resonance energy transfer in group p2 subtilisin. 2DOS is also an antimicrobial agent which exhibits activity against Gram positive bacteria such as Streptococcus pyogenes, Enterococcus faecalis, and Bacillus subtilis.

Methylation is a chemical reaction that adds a methyl group to the substrate. The Methylation of saccharide is achieved by the addition of an alkyl group to the oxygen atom adjacent to the carbonyl group in the saccharide. The saccharide becomes a methylated saccharide. Click chemistry is a form of chemoselective reactions, which are reactions that involve only one reactant and produce one product. The most common example of click chemistry is a reaction between an azide and an alkynyl, which will give rise to 1,3-dipolar cycloaddition products. Carbohydrate modification includes modifications such as glycosylation, fluorination, and complex carbohydrate synthesis. Glycosylation refers to the process by which sugars are attached to other molecules, such as proteins or lipids. Fluorination refers to adding fluorine atoms (F) onto molecules using various methods. Complex carbohydrates can be synthesized from simple sugars with carbon
