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.</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>L-rhamnose (Rha, 6-deoxy-L-mannose) (Collins, 2006) is normally bound to other sugars as a glycoside in many plant oligosaccharides and in polysaccharides. Rhamnose is also a component of the cell wall of Mycobacterium. In plants, rhamnose is found in the polysaccharide rhamnogalacturonan I, a branched pectic polysaccharide that accounts for 7–14% of the primary wall (Oomen, 2002). Rhamnose is also found in rhamnogalacturonan II, a complex polysaccharide that accounts for ∌4% of the wall in dicots (Vidal, 2000). Rhamnose is also found in chacotriose and solatriose, the glycan components of solamargine and solasonine, two glycoalkaloids with anticancer properties (Al Sinani, 2017). An understanding of the rhamnose-containing polysaccharides of the gram positive cell wall has identified the biosynthetic pathway as an attractive therapeutic target for antimicrobial drug development (Mistou, 2016).</p>
