<p>A MurNAc disaccharide</p>

<p>Kojipentaose is a glycosidic oligosaccharide that is synthesized by the enzyme phosphorylase. It is an important nutrient for many organisms, including bacteria and fungi. Kojipentaose has been found to be synthesized from the terminal sugars of teichoic acids in both Gram-positive and Gram-negative bacteria. The stereoselectivity of the synthesis may be due to enzymatic activity or the availability of chiral substrates.</p>

<p>Human milk oligosaccharide; attenuates inflammatory cytokine release</p>

<p>Oligosaccharide domain of monosialylated glycosphingolipid GM1 with an α1,2-fucosylated galactose at the nonreducing end. The moluecule is minimally expressed in healthy tissues but has high prevalence in some tumours such as small cell lung cancer (SCLC). Fucosyl-GM1 ganglioside is a potential tumour marker for SCLC and a potential antigen target for immunotherapy.</p>

<p>3'-Sulfated Lewis A sodium salt is a synthetic oligosaccharide that is used as an antigen for the diagnosis of pancreatic cancer. It is conjugated to a monoclonal antibody and binds to the Lewis A epitope on the surface of cells. 3'-Sulfated Lewis A sodium salt has been shown to be useful in bladder cancer, where it can be used as a marker for tumorigenicity. It has also been shown to stimulate selectins and increase sugar residues on cell surfaces, which may lead to increased tumor growth.</p>

<p>1,2,3,6-Tetra-O-acetyl-4-O-[2,3,6-tri-O-acetyl-4-O-(2,3,4,6 tetra-O-acetyl bDglucopyranosyl)-bDglucopyra nosyl]-bDthioglucopyranose (1) is a sugar with the chemical formula C36H62N8O24.

The saccharides are esterified with acetate moieties at the 2 positions. It contains fluorine atoms in the form of flu</p>

<p>Trehalose is a sugar that is found in many organisms, including humans. It is a disaccharide composed of two glucose units. Trehalose has been shown to be effective against infectious diseases such as HIV and malaria. Trehalose may have anti-inflammatory effects by inhibiting the production of pro-inflammatory cytokines such as tumor necrosis factor alpha (TNF-α) and interleukin 6 (IL-6). The water vapor pressure of trehalose dihydrate is higher than that of trehalose anhydrous, which may account for its greater stability under high humidity conditions.</p>
