BIOC 2580 Study Guide - Final Guide: Hemiacetal, Aldehyde, Stereoisomerism
Document Summary
Enantiomers - commonly called the left and right handed forms of a molecule. Diastereomers - monosaccharides with more than one chiral carbon atoms have stereoisomers that differ in handedness at some carbon atoms but not at others. (different at every spot except for one). Epimers - a pair of sugars that are identical except for the configuration at one carbon atom. (special case of diastereomers). Hemiacetals & hemiketals - are aldehydes and ketones that react with alcohols. Cyclization of glucose - the oh group at c-5 reacts with the carbonyl carbon of the aldehyde group to form a stable six-membered ring. Anomers - are isomeric forms that differ only in their configuration around the hemiacetal or hemiketal carbon. (i. e. a-glucose and b-glucose). Mutarotation - is the process when a solid glucose dissolves in water; it slowly converts into an equilibrium mixture of the alpha, beta, and linear forms. (approx. composition is.
