<p>The hyaluronic acid discaccharide and other enzymatically produced polymer homologs from hyaluronic acid have been of value in the study of hyaluronic acid metabolism in healthy and diseased tissues (Hascall, 2019).

The unsaturated disaccharide hyalobiuronic acid is released from hyaluronic acid by the action of hyaluronidase on umbilical cord (Weissman, 1954).</p>

<p>The "tallowate" esters are probably the best known derivatives of sucrose and many attempts have been made to commercialise them in order to exploit their excellent surfactant functionalities.  The most functional products are the mono- and diesters of the tallow acids (stearic, palmitic, oleic) with hydrophile-lipophile balance (HLB) values that lend themselves to surfactant applications in foods and cosmetics.  They also have other uses, for example in coating fruits with a semipermeable membrane that acts as a preservative.  Manufacturing economics have prevented these products from mass production and they remain in niche applications.</p>

<p>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.

<p>Galacto-oligosaccharides (GOS) are a class of oligosaccharides that consist of galactose, galactose derivatives, and glucose. They are found in the human diet as a result of lactose breakdown by gut bacteria. GOS can bind to glycoconjugates in the human body, such as glycoproteins and glycolipids, and have been shown to be effective in preventing the growth of pathogens. Galacto-oligosaccharides are also synthetically produced, using a chromatographic method that separates them into individual sugars, where they can be used for research or diagnostic purposes. The biosynthesis of GOS is also known; it is an enzyme-catalyzed reaction involving calcium ions. This process is regulated by Ca2+ signaling, which leads to an increase in the production of GOS when there is a need for more immune cells or white blood cells.</p>
