Question 1

Carbohydrates

Answer 1

Main source of energy for biological function

-Made up of sugars
-ose suffix

Carbonyl Type
-Aldehyde –> Aldose (-CHO functional group on top)
-Ketone –> Ketose (Ketone functional on top)

Question 2

Fischer Projection

Answer 2

-Open form of sugar
-Carbonyl group on top
-Hydroxylmethyl group on bottom

Question 3

D Stereoisomer

Answer 3

Last hydroxyl group of Right side of Fischer projection

-All natural sugars

Question 4

L Stereoisomer

Answer 4

Last hydroxyl group of Left side of Fischer projection

-Synthetic sugars

Question 5

Haworth Projection

Answer 5

-Closed form of sugar

Question 6

Anomeric Position

Answer 6

Position directly adjacent to Oxygen in ring

Question 7

Alpha- Anomer

Answer 7

Anomeric Hydroxyl group is DOWN on Haworth projection

Question 8

Beta- Anomer

Answer 8

Anomeric Hydroxyl group is UP on Haworth projection

Question 9

Epimer

Answer 9

Diastereomer, but only 1 stereocenter changes

Question 10

Fischer to Haworth

Answer 10

Right Side = Down
“Robert DOWNie”

Left Side = Up

Question 11

Linkage between individual sugars

Answer 11

Glycosidic bond

Beta -> Up
Alpha -> Down
