2-Acetamido-2,6-dideoxy-D-galactose (2ADG) is a structural analogue of the natural monosaccharide 2,6-dideoxy-D-galactose. It has been shown to have an antimicrobial effect against aerobacter aerogenes in vitro. 2ADG is metabolized by glycosidases and methyl glycosides to form 1,4-anhydro-2,3,4,6 tetraacetamido-2,4,6 dideoxy D galactose. This compound inhibits the growth of bacterial strains that are resistant to polymyxin b., such as Pseudomonas aeruginosa. The inhibition of these bacteria is due to the inhibition of the synthesis of their outer membrane lipopolysaccharides by 2ADG. The antibacterial activity is also attributed to its ability to inhibit the metabolism of glycan molecules in some bacteria

N-Propanoyl mannosamine is a biochemical that belongs to the group of glycoconjugates. It is an intracellular messenger that modulates the concentration of intracellular calcium and controls the release of gamma-aminobutyric acid (GABA). N-Propanoyl mannosamine has been shown to stimulate axonal growth in cell culture, which is mediated by the polysialic acid receptor. This molecule also has a role in human osteoblast differentiation and bone formation.
N-Propanoyl mannosamine can be synthesized from dopamine and erythrose via a series of reactions involving acidification, oxidation, reduction, and decarboxylation. The synthesis of this molecule requires blood group O as an acceptor.

Ulvans are structural polysaccharides present in the cell walls of green algae such as Ulva armoricana, Ulva rotondata, Ulva rigida, Ulva lacterca and Ulva pertusa.

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.
