To draw: The Haworth projection of Gentiobiose.
Introduction: Gentiobiose is the common disaccharide observed in gentians and other plants. In case of the Haworth projection, sugar is represented either as pentagon or hexagon with bonds coming off the ring. Gentiobiose is composed of two subunits of glucose linked to each other with the help of glycosidic bonds oriented in beta direction.
(b)
To draw The Haworth projection of Raffinose.
Introduction: Raffinose is the trisaccharide made up of glucose, galactose, and fructose and commonly found in sugar beets In case of the Haworth projection, sugar is represented either as pentagon or hexagon with bonds coming off the ring. Raffinose is made up of one molecule of α –D- galactose, α –D- glucose and β-D fructose linked by a glycosidic bond.
(c)
To draw The Haworth projection of dextran having one branch point.
Introduction: Bacteria produce certain polysaccharides called as Dextrans. In case of the Haworth projection, sugar is represented either as pentagon or hexagon with bonds coming off the ring. Dextrans are

Much cheaper alternative sources of omega-3 fats include fats from some seeds and nuts (most often from flax seed in consumer products), but the allure of fish oil sources maintains these products' popularity despite much higher prices. Is there a difference in the omega-3 fats derived from plant and animal sources?

- Test for Monosaccharides: Clinistix Carbohydrate molecules range from the very simple to the very complex. The word “saccharide” means sugar, while the prefixes “mono”, “di” and “poly” categorize carbohydrates according to how many simple sugar molecules are joined together to form the carbohydrate. To test for the presence of monosaccharide, we will be using Clinistix (a product that is used to test for the presence of glucose in urine). See the label (in video) for details. These test strips are used by dipping the colored end into the solution, then comparing the color to the chart on the bottle. The positive color(s) is/are __________________________. The negative color is ________________.
