BI226 Lecture Notes - Lecture 14: Mutarotation, Structural Isomer, Anomer
Document Summary
Anomers are stereoisomers that differ at the carbonyl carbon (anomeric carbon) The arrangement of the oh group around that anomeric carbon determines whether the anomer is an alpha or beta. Stereoisomers have the same chemical formula but a different spatial arrangement of the atoms around a single carbon. When we add things to monosaccharides we call them substitutions. Involves adding a functional group: complex carbohydrates. Glycosidic bond: is covalent, electrons are shared, forms between the anomeric carbon (c=0) of one monomer and an oh of the other monomer, covalent forms by loss of water dehydration. Form of stereoisomer (structural isomer with variation around one single carbon) C=0 + oh reacts = molecular movement. Forms with alpha glucose (opposite side of the c-oc) or beta glucose (same).
