<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>

In lysosomal storage disorders, such as, Tay-Sachs and Sandhoff disease, where hexosaminases A and B are deficient, GM2 ganglioside accumulates in the nervous system (Cachon-Gonzalez, 2018). GM2 ganglioside is also overexpressed in melanomas and other tumours of neuro-ecto origin (Yoshida, 2020). Moreover, the sugar moiety of GM2 ganglioside is a receptor allowing viral infection of cells with reovirus and rotavirus (Zhu, 2018).</p>

<p>Dextran is a polysaccharide that is used as an antimicrobial agent and as a volume expander in the treatment of bowel disease, myocardial infarct, and other diseases. Dextran sulfate is a linear polymer with a molecular weight of 500,000 to 1,000,000. It has minimal toxicity and does not interfere with iron homeostasis or cause fluid overload.

The mechanism by which dextran sulfate inhibits inflammation is unknown, but may involve its ability to bind to macrophages and neutrophils in the gut wall. Dextran sulfate also binds to bacteria and prevents their growth. This binding may prevent bacterial penetration into epithelial cells or block bacterial attachment to cell surfaces. The efficacy of dextran sulfate against pathogenic mechanisms such as inflammation has been demonstrated in experimental models.</p>
