Cyclic hemiacetals - Study guides, Class notes & Summaries

Primary function of carbohydrates - Fuel for body - energy and biosynthesis Classification of carbohydrates - - aldoses vs ketoses - number of carbons (ex: triose = 3 carbons) Constitutional isomers - same molecular formula, different connectivity Stereoisomers - Compounds with the same structural formula but with a different arrangement of the atoms in space. Enantiomers - mirror images of each other Distereomers - stereoisomers that are not mirror images Epimers - differ in ...

NU624 2nd Exam Practice Questions and Answers B. Haworth projections -Aldehydes react with alcohols to form hemiacetals, and ketones react with alcohols to form hemiketals—when this intramolecular reaction occurs, the linear monosaccharide forms a cyclic structure -The cyclic structures are called Haworth projections -Lower horizontal bond in the ring is projected toward you, above the plane of the page, and the upper horizontal bond is projected away from you, behind the plane of the ...
