CAS :Maltotriosyltrehalose is a sugar that is found in plants, fungi, and bacteria. It can be used as a substrate for the production of hydrogen-bonded oligosaccharides. Maltotriosyltrehalose has been shown to have a protective effect against death induced by high temperatures in mammalian cells. This sugar is also a good substrate for the production of hydrogen-bonded oligosaccharides and can be used as an additive to dry food products such as bread or cereals. Maltotriosyltrehalose is stable at high temperatures and has been shown to protect against cell death caused by heat stress. It can be used in both animal feed and human food products. Maltotriosyltrehalose is not active against proteases, but it does not inhibit the activity of mammalian cells that produce proteases.Formule :C20H52O26Degré de pureté :Min. 95%Masse moléculaire :708.61 g/molChitosan

CAS :Drug carrier for cancer therapy & imaging, biocompatible, soluble, biodegradableCouleur et forme :PowderLewis B tetrasaccharide
CAS :Lewis B tetrasaccharide (LBT) is a glycosylated oligosaccharide that is found in the outer membrane of human pathogens, such as Helicobacter pylori. LBT has been shown to inhibit the growth of cancer cells and may be used as a potential therapeutic agent for cancer treatment. It has also been shown to have structural features similar to those found in inflammatory bowel disease patients, suggesting that it may play a role in regulating bowel inflammation. LBT is recognized by monoclonal antibodies and can be used to detect H. pylori in biological samples. Lewis B tetrasaccharide binds with methyl glycosides on human erythrocytes, which inhibits the polymerase chain reaction (PCR). This inhibition leads to reduced DNA synthesis and a decrease in bacterial replication, making it an effective antimicrobial agent.Formule :C26H45NO19Degré de pureté :Min. 90%Couleur et forme :White PowderMasse moléculaire :675.63 g/mol2-O-(a-D-Galactopyranosyl)-D-glucopyranose
CAS :2-O-(a-D-Galactopyranosyl)-D-glucopyranose is a disaccharide consisting of two monosaccharides, glucose and galactose. It also contains a hydroxy group on the second carbon atom in the molecule. 2-O-(a-D-Galactopyranosyl)-D-glucopyranose is found in some plants including sugarcane, sugar beet, and sweet potatoes. This disaccharide is broken down by enzymes called beta-galactosidases into its two monosaccharides. Beta-galactosidases are used as an enzyme therapy to treat certain genetic disorders that affect the breakdown of carbohydrates.Formule :C12H22O11Degré de pureté :Min. 95%Masse moléculaire :342.3 g/molLactitol anhydrous
CAS :Lactitol is a polyol that is used as a sweetener and has the potential to cause diarrhea. It belongs to the group of sugar alcohols, which are not completely digested by humans. Lactitol is produced from lactose, which is derived from milk. The main clinical relevance of lactitol is its high intestinal permeability, low caloric value, and ability to lower blood glucose levels in diabetics. Lactitol undergoes microbial metabolism through the action of certain bacteria in the colon and can be found in products such as probiotics and food supplements. It has been shown to have beneficial effects on chronic viral hepatitis and may be used for treatment of bacterial translocation. Lactitol also inhibits pge2 production in mice with colitis, leading to decreased inflammatory responses in their small intestines and colon. This inhibition may also lead to suppression of tumor growth or promotion of apoptosis in colorectal cancer cells by inhibiting protein synthesis and cell division.br>Formule :C12H24O11Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :344.31 g/molDifucosyllacto-N-tetraose
Difucosyllacto-N-tetraose is a lacto-n-fucopentaose that has been shown to be secreted by human milk. The index of this oligosaccharide is not significantly different between breastfed and formula-fed infants, which indicates that it is not influenced by the type of infant feed. Difucosyllacto-N-tetraose can be used as a marker for the frequency of infections in neonates and infants, because its levels are decreased in cases of infection. This oligosaccharide is also related to the diversity of oligosaccharides in colostrum, as it is one component of a subset found only in colostrum samples from healthy mothers.

CAS :Ex algal/bacterial polysaccharides-value in b1-3 glucanase assays & diagnosticsFormule :C30H52O26Degré de pureté :Min. 85 Area-%Couleur et forme :PowderMasse moléculaire :828.72 g/molLipopolysaccharide - from Porphyromonas gingivalis
CAS :Lipopolysaccharide (LPS) is a molecule that is produced by Porphyromonas gingivalis. This molecule is also found in the outer membranes of Gram-negative bacteria and has been shown to have many effects on animal tissues. LPS activates HIF-1α, which leads to the production of inflammatory cytokines such as necrosis factor (TNF), and interferon regulatory factors (IRFs). These molecules signal for the production of more LPS. LPS also causes tissue growth and development by activating growth factors such as insulin-like growth factor 1. LPS also activates immune cells through signaling with chemokine receptors, promoting inflammation.Degré de pureté :Min. 95%Couleur et forme :SolidLactobionic acid ethyl ester
Lactobionic acid ethyl ester is a custom synthesis of an oligosaccharide that is modified by fluorination, methylation, and click modification. Lactobionic acid ethyl ester is synthesized from the sugar D-glucose and the monosaccharide D-galactose.
