CHEM 343 Lecture Notes - Haworth Projection, Primary Alcohol, Hemiacetal
Document Summary
One or more of the alcohol groups can be oxidized in addition to the aldehyde group. The primary alcohol is the one most easily oxidized. Aldaric acid the product obtained when both the aldehyde and the primary alcohol groups are oxidized. Hemiacetal (hemiketal) the product of the addition of one equivalent of an alcohol to an aldehyde (ketone) Acetal (ketal) the product formed when a second equivalent of alcohol is added. Anomers two sugars that differ in configuration only at the carbon that is the carbonyl carbon in the open-chain form (anomers, like epimers, are a particular kind of diastereomer) Anomeric carbon the carbon that is the carbonyl carbon in the open-chain form (the only carbon bonded to two oxygens) If an aldose can form a five- or a six-membered ring, if will exist predominately as a cyclic hemiacetal in solution. The six-membered ring is represented as being flat and is viewed edge on.
