CHEM237 Chapter Notes - Chapter 8: Glycogen, Heparin, Affinity Chromatography
Document Summary
Most abundant biomolecules: can be used for energy, structural, protective functions. Epimers are sugars that differ only by the configuration about one carbon. When a monosaccharide has 5 or more carbons in the backbone, a cyclic structure is more likely to dominate. Furanose is a five ring structure is 4 carbons and a oxygen, while a pyranose is a 6 ring structure with 5 carbons and a oxygen. Fisher projection haworth projection: carbons are numbered in a clockwise direction, hydroxyl groups on the right will point down in the haworth projection, if hydroxyl is point down its alpha if it points up its beta. Amine substitution of alcohol yield amino sugars. How to name a dissacharide on learn. Permethylation with excess ch3i modifies all free oh groups into och3. Oxidation of aldehyde can be done using cu2+, which can also be used with hemiacetal.
