<p>For more than two decades, there has been substantial interest in developing novel membrane mimics specifically targeted for the biochemical and biophysical characterization of membrane proteins. Examples include new types of detergents, such as cycloalkyl maltosides (CYMAL detergents).</p>

<p>Triisopropylsilyl 2-azido-3-O-(2,3,4,6-tetra-O-benzoyl-b-D-galactopyranosyl)-4,6-O-benzylidene-2-deoxy--aDthiogalactopyranoside is an azido glycoside that can be used in the synthesis of oligosaccharides. It has been shown to be a potent inhibitor of bacterial growth. This compound is synthesized by reacting 2-(trimethylsilyl)ethanol with 3-[(2,3,4,6-tetraacetyl bDgalactopyranosyl)oxy]propionic acid and sodium azide in the presence of triethylamine. The reaction produces a mixture of products which are purified by chromatography. This product is then reacted with benzaldehyde to produce the desired product.</p>

<p>Used for structural and conformational studies and as enzyme substrates</p>

<p>N-Acetylneuraminyl-(a2-3)-D-galactopyranosyl-(b1-3)-D-N-acetylgalactosaminyl serine is a custom synthesized carbohydrate with an average molecular weight of about 1,000. It has been modified with fluorination, methylation, and click chemistry. This polysaccharide has an acetamido group on the C6 position of N-acetylneuraminic acid and a glycosidic linkage at the C4 position of galactose. The saccharide units are composed of a 2,3-linked galactose residue and a b1,3 linked N-acetylgalactosamine residue. The CAS number for this carbohydrate is 116863-87-8.</p>

<p>Tetra-mannuronic acid sodium salt (β-1,4-linked sodium mannuronotetraose) is one of a number of oligosaccharides obtained from alginate which is a polysaccharide in brown seaweeds containing: blocks of repeating mannuronic acid sequences (M-M-M-M etc), repeating guluronic acid sequences (G-G-G-G etc), and alternating M-G-M-G sequences.  Oligosaccharides can be released using several methods (Lua, 2015; Yanga, 2004) and claims have been published that mannuronic acid oligosaccharides for example, can be effective in the prophylaxis and treatment of Alzheimer's disease, or for the prophylaxis and treatment of diabetes (USP 8835403B2, 2014).</p>

<p>GD1a (shown as sodium salt) is one of the major gangliosides in neuronal and glial membranes. It has a core tetrasaccharide structure (Galβ1,3GalNAcβ1,4Galβ1,4Glc) with sialic acids linked α2,3/α2,8 to the inner galactose residue, α2,3 to the outer galactose residue and ceramide linked β to position 1 on the reducing terminal glucose residue (Ledeen, 2009). It interacts with myelin-associated glycoprotein (MAG) and is essential for long-term axon-myelin stability. It plays a role in viral infection as it is a receptor for viral glycoproteins in rotavirus and paramyxovirus 1. The hexasaccharide GD1a moiety was also found on a glycoprotein that acts as a receptor for adenovirus type 37. GD1a ganglioside also interacts with botulinum neurotoxin and is crucial for its entry into cells (Kolter, 2012).</p>
