<p>3,4,2',3',4'-Penta-O-acetylsucrose (PAS) is a carbohydrate that has been found to be a potent inhibitor of the enzyme glycogen phosphorylase. The reductive elimination of the acetyl groups from PAS produces 2,3,4'-tri-O-acetylsucrose (TAS), which is also an inhibitor of glycogen phosphorylase. TAS inhibits this enzyme by binding to the active site and blocking access to the substrate. TAS also inhibits gluconeogenesis in liver cells by competing with glucose for uptake into the cell. In vitro studies have shown that TAS binds to boron trifluoride and lithium aluminum hydride more effectively than it does to diazomethane or detritylation.</p>

<p>The major gel forming component in agar, agarose, consists of a linear chain of sequences of 1,3 linked β-D-galactopyranosyl units and 1,4 linkages to 3,6-anhydro-α-L-galactopyranosyl units. Gelation is done via the formation of double helices (Arnott, 1974). Agar's properties are similar to gelatin as it is primarily used as a plating gel for microbial cultures (Lahaye, 1991). However, agar is a good substitute for animal-based gelatin in vegetarian foods and is easy to use in food gels in a similar way to the carrageenans. Common food applications of agar include: puddings, custards, and soft candies. Agar improves the texture of processed cheese and frozen desserts, and is also added to baked goods to inhibit staling. A creative food application uses agar-based gel cubes that are infused with fruit extract or wine to make a vegetable-based aspic (Armisén, 2009).<br>Agar contains two polysaccharides Agarobiose and Agaropectin. Both Gelidium latifolium and Gelidium amansii are sources of both Agar and Agarose. The images were kindly provided by Prof Mike Guiry from Cork who runs ‘The Seaweed Site’.<br>Agaropectin<br>Agaropectin is a sulphated non-gelling galactan comprising about 30% of Agar. Half ester sulphate is present in varying amounts plus D-glucuronic acid and small amounts of pyruvic acid. As with Agarose the main chain has alternating residues of D-galactose and L-galactose heavily modified with acidic side-groups which are usually sulfate, glucuronate, and pyruvate. Pyruvic acid is possibly attached in an acetal form to the D-galactose residues of the agarobiose skeleton. No formal structure of Agaropectin appears to have been published.<br>Agarose<br>Agarose is a linear gelling polysaccharide of (1-3) linked β-D-galactopyranose residues linked to 3,6-anhydro-α-L-galactopyranose via 1-4 bonds. Agar contains about 60% Agarose.</p>
