<p>Lewis Y tetrasaccharide is a type of antigen that is used as a pharmacological agent. It has been shown to be effective in treating carcinoma cell lines and primary sclerosing cholangitis. Lewis Y tetrasaccharide has also been shown to be an antigen for the mouse monoclonal antibody, which is used in cancer research. The Lewis Y tetrasaccharide stimulates the immune system by interacting with certain cells called dendritic cells and macrophages, which are responsible for activating T-cells. This interaction promotes the production of chemoattractant proteins, which are proteins that attract white blood cells to fight infection and promote healing. Lewis Y tetrasaccharide has also been shown to cause cancer cell death by lysing cells through apoptosis or necrosis depending on the tissue type.</p>

<p>Glycosaminoglycans (GAGs) are polysaccharides that are found in the extracellular matrix and on the surface of cells. GAGs consist of a linear chain of repeating disaccharide units, with one or more sugar molecules linked by a glycosidic bond. They have been shown to be important for the function and structure of tissues, including those in the gastrointestinal tract. GAGs have been shown to stimulate cellular growth, regulate inflammatory responses, and promote wound healing. They have also been shown to inhibit activity of polymorphonuclear leucocytes (PMN), which play an important role in inflammation. One type of GAG is dextran sulfate, which has been used as a biological scaffold for tissue engineering applications. Glycosaminoglycans may also play a role in regulating immune responses through interaction with toll-like receptor 4 (TLR4).</p>

<p>Lipopolysaccharides are a heterogeneous group of molecules that include endotoxins, lipid A, and core oligosaccharide. They are released from the cell wall of gram-negative bacteria as a result of bacterial lysis. Lipopolysaccharides are potent activators of immune cells, inducing the secretion of pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). TNF-α is also known to induce the production of other pro-inflammatory cytokines including IL-6, IL-8, IL-10, and IL-12. Lipopolysaccharides have been shown to cause liver damage in animals by increasing plasma alanine aminotransferase levels. This may also be due to their ability to induce the production of malondialdehyde and c-reactive protein.</p>

<p>Lewis Y-PAA-biotin is a complex carbohydrate which is synthesized using Click chemistry. This compound has been modified to include a biotin moiety. Lewis Y-PAA-biotin has been shown to be resistant to enzymatic degradation and can be used as a saccharide in the synthesis of polysaccharides. Lewis Y-PAA-biotin is synthesized by attaching poly(acrylamide) (PAA) chains to the sugar moieties of Lewis Y. The carbonyl group on the PAA chains can be fluorinated, which makes it useful for click modification reactions with fluorinated compounds.</p>
