Unformatted text preview: or D- enantiomer, downward for L- enantiomer Beta projection: same side as - CH2OH Alpha projection: opposite side as - CH2OH Mutarotation: the α and β anomers of D- glucose interconvert in aqueous solution, in which one ring form opens briefly into linear form and then closes again Hexose derivatives: in which the hydroxyl group of parent compound is replaced with another substituent, or carbon atom is oxidized Aldonic acids: oxidized aldoses O- glycosidic bond: bond that joins covalently two monosaccharides When a hydroxyl group of one sugar molecules, typically cyclic, reacts with the anomeric carbon of the other N- glycosyl bond: joins anomeric carbon of a sugar to nitrogen atom in glycoproteins Carbonyl carbon can only be oxidized when the sugar is in its linear form Reducing end: end of chain with free anomeric carbon Starch: contains two types of glucose polymer, amylose and amylopectin Amylose is unbranched and linear (α14) Amylopectin is branched (α16) occur every 24- 30 residues Glycogen: main storage polysaccharide of animal cells More ext...
