Monday, February 01, 2010 Table Sugar [Disaccharide] Sucrose – made up of glucose and fructose [Monosaccharides] A) Number of carbons B) Location of carbonyl group -Aldoses – have an aldehyde group at one end [glucose] -Ketoses- have a keto group internally [fructose] C) Varying configurations of hydroxyl groups Oligosaccharides Approximately 2-10 monosaccharides linked by glycosidic bonds. [Disaccharides = most important] Maltose is connected by a 1-4 glycosidic bond between 2 glucose molecules. Sucrose is connected by a 1-2 glycosidic bond between a glucose and a fructose molecule. Lactose is glucose + galactose. Types of polysaccharides Storage polysaccharides -Glycogen, Starch, Dextran Structure polysaccharides -Cellulose, Chitin Starch – storage polysaccharide of plants, 2 types of starch. Amylose, amylopectine. [both polymers of

Unformatted text preview: glucose] both 1-4 linkage. Both are alpha forms (means that the hydroxyl is below). Amylopectin has a 1-6 branch , 1 per 30! Glycogen- much more branching. [at 1-6] Cellulose/Chitin – beta glycosidic linkage. Straight. No branching. Parallel fibers. 1-4 linkage. Between chains, small hydrogen bonds. Chemically modified carbohydrates Sugar phosphate-Fructose 1, 6 biphosphate-Glucose 6 phosphate Amino sugars-glucosamine, galactosamine-amino group instead of a OH Chitin-polymer of N acetyl glucosamine *know the N acetyl glucosamine picture [has presence of Nitrogen] Chitin- found in exoskeleton of arthropods. Can be used as surgical threat. Strong as cellulose. Splenda/Sucralose- Another function of polysacch. Identity – glycoproteins : identification badge for cells....
