This beta-cyclodextrin (β-CD) derivative is a functionalized cyclic oligosaccharide composed of seven glucose units, characterized by a hydrophilic exterior and a lipophilic cavity (bigger than α-CD and smaller than γ-CDs), which allows it to encapsulate various guest molecules. This structural feature facilitates its use in multiple applications, including pharmaceuticals, food enhancement, and cosmetics. In the pharmaceutical industry, it enhances the solubility and stability of poorly water-soluble drugs, improving their bioavailability and efficacy while also masking unpleasant tastes. The food sector utilizes it as a stabilizer for flavors, colors, and nutrients, extending shelf life by protecting sensitive ingredients from degradation. In cosmetics, it serves as a complexing agent for fragrances and active components, ensuring their stability and controlled release. Its use expands to many other fields, including nanotechnology for drug delivery systems, environmental remediation for extracting organic pollutants, textiles for slow-release fragrances, and analytical chemistry for chiral separation.

Amylopectin is composed of between 2,000 to 200,000 glucose residues linked α (1→4) with α (1→6) branching. The molecule is highly branched, every 24 to 30 glucose units, resulting in a soluble molecule with many terminal residues. Starch is made of about 70% amylopectin by weight, though it varies depending on the source (higher in medium-grain rice to 100% in glutinous rice, waxy potato starch, waxy corn, and lower in long-grain rice, amylomaize, and russet potatoes).

Nigeran is a polysaccharide found in the cell wall of lower fungi. In certain Aspergillus and Penicillium spp., nigeran was first isolated from Penicillium expansum and Aspergillus niger (illustrated). The polysaccharide contains unbranched α-D- glucopyranose residues linked 1,3 and 1,4. Nigeran is part of the hyphal cell wall, where it can contribute up to 40 % of the cell dry weight. The polysaccharide occupies several domains or location on the hyphal wall and is highly crystalline in vivo. Deposition of nigeran is primarily at the outer surface of the hyphal wall.

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).

1,2,3,4,6-Penta-O-acetyl-α-D-mannopyranose is an acetylated sugar which is used as an intermediate in the mannosylation of glycoproteins or glycoconjugates. It can be used in the production of mannosylated glycoconjugate vaccines or lipid nanoparticles (LNPs) which have been investigated for improving antigen up-take mediated, via the mannose receptor (MR) of human antigen presenting cells (APCs).  1,2,3,4,6-Penta-O-acetyl-a-D-mannopyranose, also known as α-D-Mannose pentaacetate, has also been used in the study of isolated rat pancreatic islets where it stimulates insulin release.
