L-Glucono-1,4-lactone is a substance that belongs to the group of compounds known as alpha hydroxy acids. It is produced in the body by an enzyme called l-gluconolactonase and is present in small quantities in many fruits and vegetables. L-Glucono-1,4-lactone has been shown to prevent skin aging and protect against UV light damage through its antioxidant properties. This compound can be found in sunscreens or it can be taken orally to provide protection from the sun. Clinical data on L-Glucono-1,4-lactone treatments are not yet available.

4-(b-D-Mannopyranosyl)-D-rhamnose is a glycosylation agent that can be methylated and fluorinated. It is also capable of being modified with the Click reaction to add polysaccharide or oligosaccharide moieties. 4-(b-D-Mannopyranosyl)-D-rhamnose is an important building block for complex carbohydrates, which are important in many aspects of life. This product is available in custom synthesis, high purity, and CAS No.

2-Deoxy-2-trifluoroacetamido-D-glucose (dTFA) is an acetal that is formed from the reaction of trifluoroacetic acid with 2-deoxy-2-trifluoroacetamido-D-glucose. This compound yields aldehydes, and can be used to form glycosidic bonds. It also has the ability to react with amino groups on peptides and proteins, forming acetals. 2-Deoxy-2-trifluoroacetamido-D-glucose has been shown to have a variety of functions including being a carbohydrate, an acetal, and an inhibitor of peptide bond formation.

Phenyl-beta-D-glucopyranoside is a phenolic compound that can be found in plant cell walls. It is a monosaccharide with an ester linkage, which is hydrolyzed by esterases to yield protocatechuic acid. Phenyl-beta-D-glucopyranoside is an inhibitor of sugar transport and has been shown to have protective effects on the liver when it is exposed to toxic substances. This sugar also binds to proteins, which may alter the function of these proteins. Phenyl-beta-D-glucopyranoside has been shown to inhibit glycolysis in hepatic tissues and tannins are released from erythrocytes treated with this substance. Phenyl-beta-D-glucopyranoside has been shown to be chemically stable under acidic conditions.

A custom synthesis of a complex carbohydrate. It is a synthetic, modified and fluorinated saccharide with a methylated monosaccharide.

1,3,4,6-Tetra-O-acetyl-2-[(2-aminoacetyl)amino]-2-deoxy-a-D-glucopyranose is an example of a sugar that has been modified by fluorination. This modification takes place at the 2 position of the sugar's aldehyde group. It is also an example of a monosaccharide with a glycosylation site at C1' and an acetylated hydroxyl group on C6'. The chemical name for this sugar is 1,3,4,6-Tetra-O-(2-(N-[2-(glycolyl)amino]acetyl)-N-[3-(glycolyl)amino]propionyl)-2-[(2-(N-[2-(glycolyl)amino]acetyl)amino]-2-deoxy--aD--glucop

Xylan is the most abundant noncellulosic polysaccharide present in both hardwoods and annual plants. Xylan is found mainly in the secondary cell wall as part of the hemicellulose complex and forms an interface between lignin and other polysaccharides. In their simplest forms, xylans are linear polysaccharides of β-1,4-xylose residues but can also form complex heterogenous and polydispersed glycans.
