<p>Heparin is a carbohydrate that is derived from the mucopolysaccharide heparin. It is a complex carbohydrate that consists of a chain of alternating N-acetylglucosamine and glucuronic acid. Heparin is used as an anticoagulant to prevent blood clotting, which may occur due to injury or during surgery.

Recently, it has been modified with a fluorine atom on the sugar ring, which increases their solubility and bioavailability. Click chemistry can be used to attach other molecules to the saccharide ammonium salt in order to modify the properties of heparin. This modification can be done with methyl groups or glycosyl groups, and it can also be done with other sugars such as galactose or glucose.</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>
