Question
The Koenigs–Knorr reaction forms one of these bonds with the aid of silver carbonate. For 10 points each:
[10m] Name these bonds in which an ether joins a carbohydrate molecule to another group. Cellulose consists of glucose monomers attached via beta-1,4 examples of these bonds.
ANSWER: glycosidic bonds [or glycosidic linkages]
[10h] Glycosidic bonds connect a hydroxyl carbon with one of these two moieties common in sugars. The addition of a [emphasize] single alcohol to an aldehyde or a ketone creates these two groups, whose names are prefixed to reflect this. Name either.
ANSWER: hemiacetal OR hemiketal [reject “acetal” or “ketal”]
[10e] This six-carbon sugar appears naturally as a cyclic hemiketal. This sugar, which is joined to glucose via an alpha-1,2-glycosidic bond to form sucrose, is found in high percentages in a sweetener used as a corn syrup.
ANSWER: fructose [accept high-fructose corn syrup]
