Exam III Starch - one reducing end and branched has enzymes that act on non-reducing to ease clipping Amylase - alpha 1-4 glucoses --can become circular and hydrated = fibril Amylopectin – alpha 1-4 glucoses w/ alpha 1-6 branches every 30 glucoses Glycogen - same as starch but more highly branched- circular all outside non-reducing Cellulose - beta 1-4 glucoses with H bonding at C3 Chitin - beta 1-4 N-acetyl-glucosamine H bonding like cellulose—excludes water Glycosaminoglycans-1 - GlcNac or GalNac in polymer–very negative charge Glycoprotein - oligosaccharide covalently bound to protein Proteoglycan - uronic acid containing protein Asparagine-linked (N-) glycoproteins – added in the lumen of rough ER Glycolysis Preparatory Phase : ATP used Step 1: Hexokinase phosphorylates the oxygen on carbon 6 outside ring = Glucose-6-Phosphate Hexokinase- cleft closure upon binding of glucose- dehydrates so H2O cannot be nuc Step 2: Enzyme- Glucose-6-(P) Isomerase – H taken off C2 to make C=C. C2’s OH loses H
