Methylation of a saccharide with a methyl group is called methylation. The process is used in the synthesis of many important molecules, including biomedically-relevant compounds such as drugs and natural products. Methylation can be achieved by using various methods, such as by using an organometallic (e.g., Grignard reagent) or electrophilic reagent (e.g., dimethyl sulfate).

2-C-Hydroxymethyl-D-ribose is a sugar that has been found in the cell wall of Mycobacterium tuberculosis. It is also found in some other bacteria, such as Streptomyces coelicolor. 2-C-Hydroxymethyl-D-ribose may be involved in the synthesis of glycan and may have a role in the molybdenum cofactor biosynthesis pathway. This molecule has been shown to have acidic properties, which are most likely due to its hydroxyl groups. The 13C NMR spectrum for this compound shows three peaks at δ H = 138.2, 144.3, and 154.5 ppm corresponding to the ribofuranoside moiety. The skeleton of this molecule was rationalized by attaching an acetaldehyde group to the 2'-hydroxyl group on position C2 of ribose, which is consistent with the observed 13C NMR spectrum. This molecule has

N-Methyl-D-glucosamine is a nucleotide that is found in the adenine nucleotide pool. It can be synthesized from glucose, which is converted to glucosamine-6-phosphate by the enzyme glucosamine synthetase. This compound can also be obtained from dietary sources. N-Methyl-D-glucosamine has been shown to have cytotoxic activity against mouse tumor cells and inhibit skin cancer in mice. It binds with DNA and inhibits cell growth through a glycosidic bond with terminal residues of DNA, preventing transcription and replication. N-Methyl-D-glucosamine has also been shown to inhibit the growth of resistant microorganisms such as C. glabrata, including antibiotic resistant strains, and bacteria such as E. coli and P. aeruginosa when used in combination with an experimental model of biocompatible polymers.

2-Acetamido-1,6-anhydro-2-deoxy-b-D-glucopyranose is widely used in carbohydrate chemistry. It is used as reagent for the synthesis of oligosaccharides and also as a precursor in the synthesis of oligopeptides. 2-Acetamido-1,6-anhydro-2-deoxy-b-D-glucopyranose is an analog of levoglucosan, a compound that is often used to trace for biomass burning in enviromental chemistry studies.

4-Methoxyphenyl 2-acetamido-4-O-(2,3,4,6-tri-O-acetyl-b-D-glucopyranosyl)-3,6-di-O-benzyl-2,3′:6′,4′:5″,6′″:5″′:3″″:4″″′:5″″′:6′″′-[1]benzothiadiazole (MTBT) is a synthetic monosaccharide sugar that is modified to have a 1,2,3,4,5 and 6 benzothiadiazole group. MTBT is a complex carbohydrate that is synthesized through methylation of the sugar followed by a click modification. It has been used in the synthesis of oligosaccharides and polysaccharides.

L-Altrose is a carbohydrate that is used as a nutrient and sweetener. It is a dextrose monomer with an L-arabinose side chain. L-Altrose has been shown to be a stereoselective carbon source that can be used in the synthesis of various biologically active compounds, such as antibiotics. L-Altrose has also been shown to stimulate growth of yeast cells in the absence of oxygen by providing an extracellular carbon source. This compound can be hydrolyzed by ring-opening or benzoylation reactions to yield dextrose.

Lacto-N-triose I is a carbohydrate antigen that is used as an acceptor in the synthesis of trisaccharides. Lacto-N-triose I has been shown to have acidic hydrolysis and gel permeation chromatography. It can be used for the synthesis of oligosaccharides, which are important for glycosylation reactions. Lacto-N-triose I also has a glycosylation reaction that can be activated by desulfurization.

An α-anomer, obtained by crystallization at low temperature, can be dehydrated to stable form above 130°C or an unstable (hygroscopic) form at lower temperatures. An example of the applications for α-Lactose monohydrate is in dry powder inhalers.  These are devices that deliver medication to the lung in the form of a dry powder generating an aerosol directly from the drug powder or mixture, using an excipient such as lactose monohydrate.

Heparin is a carbohydrate that is derived from the mucopolysaccharide heparin. It is a complex carbohydrate that consists of a chain of alternating N-acetylglucosamine and glucuronic acid. Heparin is used as an anticoagulant to prevent blood clotting, which may occur due to injury or during surgery. Heparin's use in medicine has been limited by its low solubility and rapid clearance from the body. Recently, it has been modified with a fluorine atom on the sugar ring, which increases their solubility and bioavailability. Click chemistry can be used to attach other molecules to the saccharide ammonium salt in order to modify the properties of heparin. This modification can be done with methyl groups or glycosyl groups, and it can also be done with other sugars such as galactose or glucose.

Calcium-D-arabonate is a fatty acid that is used as a functional ingredient in the food industry. It has been shown to increase the rate of reactions, such as glycosidic bond cleavage and polymerization, by acting as an oxidation catalyst. This product also has a high molecular weight and can be used to modify the structure of polymers. Calcium-D-arabonate is often used in model systems because it reacts with other substances at a pH optimum of 6.0-7.5.

Curdlan is a microbial polysaccharide produced by a mutant strain of Alcaligenes faecalis var. myxogenes which was first shown to produce succinoglucan prior to mutation. Curdlan is a β-1,3 glucan forming clear solutions at about 55 °C which then gels (“low-set”) when cooled. Suspensions of curdlan at higher temperatures form firm resilient gels (“high set”) that melt at 140 - 160 °C.
